Research on Deepening Design and Construction of Cross-Sea Tunnel Based on the Principle of Prefabricated Building

With the development of the economy and the rapid progress of the construction level, the construction of the cross-sea tunnel began to gradually promote and further promoted. China gradually ushered in the peak period of undersea tunnel construction, has built xiamen, Qingdao, guangzhou, Shanghai chongming island and other undersea tunnels. However, due to the late start of cross-sea tunnel construction compared with western countries, there is still a lack of certain construction experience, especially in the construction of cross-sea tunnel. The construction of the cross-sea tunnel has put forward higher requirements on the construction level. In terms of the design and construction of the cross-sea tunnel, China is still in the initial stage of exploration and still needs unremitting research. Based on this deepening design and construction of cross-sea tunnel has become the focus of research. Based on the principle of prefabricated building and relevant calculation with the GO method, this paper calculates the reliability and risk of prefabricated building in the construction of cross-sea tunnel, and puts forward the deepening design and construction method of cross-sea tunnel on this basis. On the one hand, it is beneficial to the further development of cross-sea tunnel construction in China. On the other hand, it provides a certain theoretical basis for future research on related aspects.
