The development of nuclear energy causes will inevitably produce a certain amount of radioactive waste. Among them, high -release waste has the characteristics of strong radioactivity, large toxicity, and long half -life. Major strategic topics.

At present, the internationally believes that the method of technology is deepened, and the high -tech waste will be buried in a stable geological layer from 500 meters to 1000 meters from the surface of the surface. Through multiple barrier systems For a long time, effective isolation with the human survival environment.

my country's high -release waste geological disposal library has adopted a "three -step" development strategy, that is, the site selection of the disposal library, the scientific research and disposal library construction of the underground laboratory. Among them, the scientific research of the underground laboratory shoulders a series of heavy tasks such as the appropriate evaluation of site sites, the research and development of disposal technology, and the long -term safety of disposal libraries. It is an essential key issue that is enlightened and down in the entire research and development process.

Beishan, Gansu is the Gobi uninhabited area north of the Hexi Corridor with tens of thousands of square kilometers. After a comprehensive election, in 2011, Beishan was identified as the preferred preparation area for high waste disposal in my country. It was also this year, and I resigned from the position of associate professor of the Central University of Science and Technology of Nante Central University of France and walked into Beishan.

For more than 10 years, I have undertaken more than 10 major national scientific research topics. The most important task is to promote the implementation of the underground laboratory and achieve the following aspects of scientific research results.

For the first time in the world, a quantitative high -tech waste disposal method is proposed. This method considers not only the constructionability of the rock body itself, but also the requirements of the long -term safety of the disposal library on the characteristics of the surrounding rock, which has been well received by the relevant authoritative experts of the world.

Leading the project and scientific research team has built the Beishankeng detective facilities, completed more than 10 large -scale on -site experiments, and mastered the key technical system required for the construction of underground laboratories.

The system of indoor experiments of the system was carried out, revealing the long -term mechanical behavior characteristics and its evolutionary mechanism of Beishan granite under multiple coupling conditions, and then established corresponding theoretical models and long -term stability data analysis methods. The layout of the main structure of the laboratory and long -term security have been demonstrated and optimized.

Based on this series of scientific research results, in 2019, we proposed the construction and scientific research plan of the underground laboratory in China High -Plaza waste disposal, and obtained the formal approval of the state. At present, the entire project is progressing very smoothly, the main project has begun, and on -site experiments will be fully developed. In the future, Beishan will usher in 37 top scientific research teams in China to fight side by side.

Guard the safety of the city with counting wisdom

(Deng Yiqi)

My team and I mainly focus on the application of artificial intelligence in the field of public safety. Specific research contents include related data standards, algorithms, core parts, whole machine equipment, and some services related to this.

Today, artificial intelligence that everyone feels may be concentrated in applications such as personal new consumption or intelligent driving. In fact, since the day of artificial intelligence, it has been inseparable from public safety. From the "three stations and one game" of the "three stations and one game" to the testing of urban land, the surveillance of FOD runways FOD runway, and electricity inspection of the airport, artificial intelligence is widely used.

If the light of the electromagnetic band that the person’s eyeballs are not seen as an invisible light, what our team does is to study how to use these invisible light to better observe, study, and analyze the properties of substances, so as to find in public safety in advance in public safety Some potential risks are predicted.

We try to create a smart public security perception and guarantee system for cloud -side collaboration through artificial intelligence, the Internet and other related technologies, and solve the problems of inconsistent data standards in public safety, slow detection speed, incorrect linkage, high labor costs, and difficult data traceability. , Turn the data islands into a smart island, make the business "look back" into "currently run", so that public safety can be visible, considerable, and controllable.

With the concern and support of leaders at all levels of provincial and municipalities, we have established a common technology research platform relying on overseas and domestic universities, at the same time established a platform for scientific and technological achievements, and formed a manufacturer in related fields in the local area to form a small and medium -sized technology enterprise for manufacturers. R & D, large -scale state -owned enterprises, central enterprises and listed enterprises undertake the coordinated production mechanism of production tasks. At the fastest speed, we have completed the entire process of successful response from customer needs to the successful design, production, manufacturing, delivery, and debugging of the relevant design, production, manufacturing, delivery and commissioning. At present, our business scope is east to Shanghai, west to Kashgar, north to Harbin, and north to Beihai, including key bayonets including airports, logistics bases and subway stations. We have achieved effective real -time identification of various types of dangerous goods and prohibited products, and have cumulatively dealt with more than 10,000 public safety hazards. Under this premise, our pass rate has also increased by 59.3%, which has saved the average human cost of more than 30 million yuan per year for each service unit.

We hope that through unremitting efforts, we will create a new model of public safety precautions that cover the whole domain and full time, integrate the full band, realize the multiple public safety prevention prevention of public safety, and use the countless wisdom to protect the safety of the city.

In the depths of the 12 -year Dream Shield Tunnel, promoting the spirit of craftsmanship

The shield machine is the mainstream high -tech equipment in the field of tunnel and underground engineering construction. It has as many as 50,000 parts, and more than 30 subsystems of more than 30 systems of hydraulic pressure, machinery, electrical, fluid, and circulation.

In the summer of 2010, I entered the Ningbo Metro Line 1 of the China Railway Tunnel Bureau to first contact the shield machine on the project. Facing this high -tech and complex equipment, I feel challenging.

In the more than 3,700 days and nights of the construction site, in the face of high temperature, dust, humidity and noise, I have to stick to it for more than 10 hours a day. Over the past 12 years, I have read more than 100 million words of technical information, and combined with the actual construction reality, I recorded construction data, carefully drawing graphics, summing up construction experience lessons every day, and gradually grasped the technical points of the shield construction.

The driver of the shield is the driver with the slowest driving speed in the world, but our struggle facilitates people's daily travel and has opened the "acceleration" of urban development. My China Railway Tunnel Bureau is a national team constructed by the State Council in 1978 in the field of gathering tunnels and underground engineering. It has 130 sets of TBM and shield machines. Similar construction enterprises.

Under this platform, I participated in the construction of 11 national key projects in 12 years. From the soil pressure shield to the mud shield to TBM, from the small diameter shield to the large diameter shield, from the "foreign character" shield to the "national character" shield, I participated in and witnessed the Chinese shield business obedience. Running to leading, then the big development of overseas. At the same time, I also grew from a fledgling apprentice to a technical expert.

In October 2016, the "Mother Yongqi Shield Operation Skills Master Studio" named after my name was established. The studio aims at "focusing on promoting the spirit of model workers and the spirit of craftsmanship, concentrating on solving the technical difficulties of large diameter shields, and professional cultivation of large -diameter shield technical talents", which has made significant contributions to corporate shield technology innovation and shield technical talent cultivation.

In terms of technological innovation, the studio conducts scientific research and research on key technical difficulties in the construction of high water pressure, large diameter mud shield construction, and 34 innovation results, solving the problems of many key technologies for the construction of large diameter shield tunnels, filling the domestic complexity or not The gap in the construction of the water bottom tunnel of the uniform strata, the large diameter of the large diameter, and the construction of the water bottom tunnel has created more than tens of millions of yuan for enterprises.

In terms of talent training, through the "bidding belt", more than 20 shield drivers are cultivated for enterprises, and they have been named "Locomotive Modeling and Craftsman Talent Innovation Studio" by the National Railway Federation of Railway. The fertile soil cultivation of talents.
