Influence Of Surrounding Shallow Foundation By Shield Construction In Formation And Disaster Control Technology

In this paper, the south of Nanjing Metro Line extension fork in the road to Nanjing South Station Project as the background interval,do analysis on the effect of surrounding ground surface an shallow foundation by shield tunneling method respectively;use finite element software to simulate the effect of shallow foundation by shield tunneling method.do analysis on the effect of surrounding ground surface an shallow foundation by shield tunneling method in any conditions. The main results are as follows:(1)By the observed data and numerical simulation, summarize the law of the effect of surrounding ground by shield construction.(2)By the observed data and numerical simulation, compare different working conditions, summarize the law of the effect of surrounding shallow foundation by shield construction.(3) Through the statistical parameters in actual construction process, summarize practical experience,obtained parameters of the tunnel shield the principles and rules set in the complex construction.Provide disaster control technology for the effect of surrounding shallow foundation by shield construction.
