Those things about deep -sea building 丨 cold eyes reading

my country's coastline is long and has abundant marine resources. With the key project of the Guangdong -Hong Kong -Macao Greater Bay Area, "The Modern Correction Corridor Planning of the Yangtze River Economic Belt", "Development Plan for the Development Plan for the Development Plan for the Development Plan for more high -quality integrated transportation in the Yangtze River Delta region", New requirements have been put forward on the high -quality construction of the coastal cross -sea channel in my country. The tunnel is one of the main ways of cross -sea channels. The Xiang'an Underwater Tunnel of Xiamen City, Xiamen Metro Line 3 crossing the sea tunnel, the Jiaozhou Bay Tunnel of Qingdao City, Shandong Province, Qingdao Metro Line 8 Cross -sea Tunnel, Hong Kong -Zhuhai -Macao Bridge Underwater Tunnel and other major underground tunnel projects , my country's tunnel construction technology is becoming more and more improved. However, under the conditions of high earthquake intensity areas, extremely hard and hard -to -equal and complicated strata, build a large broken underwater tunnel with a shield method. For tunnel structure design, earthquake resistance design, disaster prevention and rescue design, etc., it is still a new one. challenge. The book "Survey and Design and Key Technology" published by the People's Transportation Publishing House Co., Ltd., "High -Instance Area Shantou Bay Tunnel Engineering Survey and Design and Research and Research on the Survey and Design and Key Technology" is a large underwater shield in Shantou Bay in the high earthquake intensity zone (8 degrees) Shantou Bay. Summoning of tunnel innovation results and key technologies. In 2007, the feasibility research work of the Shantou Bay Tunnel Project was launched. After 9 years of preliminary research, survey and design preparation, the project was officially started in 2016. In 2020, the Shantou Bay Tunnel runs through. Facing the five major environmental characteristics of the Shantou Gulf Tunnel "Large, Shallow, High, Hard, and Insurance", the Survey and Design Institute of the China Railway Tunnel Investigation and Design Institute in the sea area survey, deep tunnel burial, height tunnel earthquake resistance, durability, mechanical and electrical system, disaster prevention and mitigation, and water Lower hard rock excavation has carried out in -depth technical research. The engineering application of the research results has good effects, overcoming many technical difficulties, and promoted the development of the construction of a large diameter seabed shield tunnel technology in the highly soft and hard area, and the underwater shield is constructed by the high earthquake intensity zone and under the conditions of extremely complex environmental conditions. Survey and design technical system for construction tunnels. The project has obtained more than 10 invention patents and won the "2021 Outstanding Engineering Award" of the International Tunnel and Underground Space Association. This book truthfully records the solutions, technical solutions, and implementation points of many complex technical problems, and comprehensively summarizes the valuable first -line engineering experience and breakthrough practices of the author's team. Engineering and technical personnel who can engage in engineering design, construction management and technical research on underwater tunnels can also provide technical reserves for major engineering construction such as Qiongzhou Strait Channel, Bohai Bay Channel, and Taiwan Strait Channel in the planning and research.
