The nation's maximum reduction of seismic medical buildings in Sichuan Investment in Sichuan Investment and Delivery

Recently, the Sichuan -Investment Xichang Hospital, which was designed by the China Construction Southwest Hospital and the first bureau of the China Construction South Hospital, was completed and delivered. Sichuan Investment Xichang Hospital is the largest seismic medical building in the country. After being put into use, it will become an international three -level comprehensive hospital in the region and meets the needs of multiple levels and diversified needs. The level helps to realize the medical vision of the Liangshan Yi Autonomous Prefecture "serious illness".

Sichuan Investment Xichang Hospital is located in Xichang City, the capital of Liangshan Yi Autonomous Prefecture, Sichuan Province. Xichang was an important post on the ancient Southwest Silk Road and the ancient tea. The only aerospace base that can launch the earth synchronous satellite. The Sichuan Investment Xichang Hospital, which is located here, is a demonstration project of the "State -owned Enterprise Entering Liang" industrial poverty alleviation demonstration project in the Liangshan Yi Autonomous Prefecture, and the nation's largest shock -cut medical building. base.

Behind the high -quality completion and delivery of this lean earthquake -building hospital, the builders of China Construction have been consumed for 37 months to overcome many difficulties such as epidemic, seasonal disaster weather, lack of resource supply, and complex geological structure. A multi -functional modern tertiary A comprehensive hospital integrating medical, teaching, training, and scientific research, China Construction Blue stunned Xichang, the famous Sun City, Moon City, and Aerospace City.

Refinement design

Multi -dimensional three -dimensional weaving "Seismic Safety Network"

The Sichuan -Increasing Xichang Hospital is less than 200 meters away from the Sichuan Anning River earthquake. It belongs to a 9 -degree high -intensity defense zone and a high -rise building area of ​​Class B. Its structural design belongs to super -level high -level buildings with a high -level height.

The project manager Du Fei introduced that the occurrence of earthquake intensity above 7 degrees is a high -intensity earthquake. If the earthquake intensity reaches 9 degrees, the ground will be severely damaged. The rails of the rails may be distorted.

△ BIM model

During the design stage, the project uses BIM technology to simulate the earthquake force of hospitals to analyze in detail according to different intensity. BIM simulates the force of earthquake, and has obtained an important shock absorption coefficient and response spectrum analysis coefficient. These two types of data have a great relationship with the successful construction of the project. After the repeated comparison experiments of a variety of combined structure forms, the project team finally decided to use the shear shear wall structure of reinforced concrete frameworks with basic earthquakes, and comprehensively set the lead core septum, rubber, viscosity, and upper structure BRB flexion. A series of shock -reduction measures such as restraint support, core tube -type steel pillars and steel plate shear walls, a series of "combination boxing" of "combination boxing" is the nation's maximum "seismic safety network" of the weaving of the largest seismic medical building.

Cao Bo, the chief engineer of the project, said: "From the analysis of BIM technology simulation stress analysis, it can be seen intuitively that under the action of rare earthquake destructive power, the structure of non -seismic building structure will suffer from overall collapse. Under the simulation of the same level of seismic force, no damage or small damage under the simulation of the same level of seismic force, which fully illustrates the BIM -based technology -based seismic design, which is not only a highlight of the project, but also an important guarantee for the safety and reliability of the building structure ","

The design leads the construction and construction. The project team has begun to consider the planning from the design session. It has a good extent to the minimum shock absorption and earthquake -resistant early design to escort the efficient construction and accelerated investment and guarantee for the Sichuan Investment Xichang Hospital.

Seismic

Help the people of western Sichuan "doctors with diseases"

In order to apply important earthquake theory data obtained in the experiment to the greatest extent to promote the efficient construction of hospitals. In response to the special geology of the hospital, the project team adopts the overall seismic construction method of the project. The shock layer is set with 517 ultra -large diameter lead core septum rubber supports and 80 horizontal velocity sticky closer, which steadily supports the upper structure of the entire hospital.

△ Building building shock diagram

Lead -leading seismic rubber support and sticky damping device are important facilities for the construction of seismic projects. Lead core seismic rubber support is composed of layer -shaped rubber, steel plates, and absorbed energy -consuming lead cores. The lead core "digested" the intensity and stiffness of the body swing when the earthquake comes. Under the role of force, as much as possible or smaller deformed, so that more than 80%of the earthquake energy cannot be passed to the upper part of the seismic layer. Move, do not move "or" Dama Moving, Lou Xiaoming ". The maximum diameter of the lead -core rubber vibration branch adopted by the hospital reaches 1.4 meters, the weighing is 4.5 tons, the width of the upper and lower installation plates is 1.5 meters, and the height of the support is 0.52 meters. At the same time, it can also meet the needs of the project's 9 -degree seismic anti -intensity.

The adhesive damping device is an "artifact" that resists and reduces the destructive power of the earthquake. Its internal is like a car engine, which is used as a car engine, which is used as a car engine. composition. When the building structure produces a slight deformation, the piston and the cylinder are relative to move, forcing the damping medium to flow in the small holes or gaps, and the vibration energy consumes energy through the stagnation to reduce the further deformation of the building structure. At the same time, in order to overcome the difficulties of transportation and hanging damping device in a small space, the project team specifically designed the damping vehicle by the damping device, which is tailor -made for the workload of the damper transportation and vertical lifting.

Lead -leading seizure rubber support and sticky damping device. The application of these two "fixed buildings" is to maximize the hospital's "ground motion, no building", which greatly guarantees the normal use and medical staff of the building's body and medical staff.Safety.

The application of Sichuan Investment Xichang Hospital will strongly improve the medical treatment level of Xichang and even Liangshan Prefecture, which will greatly alleviate the medical needs of the local people."Three medical integration concepts.After the operation of the hospital, it can also provide employment opportunities for more than 3,000 people to attract high -end medical talents at home and abroad to gather Xichang, helping Xichang and the entire Liangshan Prefecture's high -quality development.
