The Influence Of Different Excavation Methods On The Surrounding Environment Of Deep Foundation Pit

With economic development, social progress,population increasing, traffic become more and more serious,the MTR as tools is to reduce traffic pressure rising rapidly in major cities, and therefore generated a lot of deep foundation pit Engineering. deep excavation will cause the surrounding surface subsidence, increase the deformation of the retaining structure, increase stress and strain around bridge piles, serious damage will speed up the bridge piles, seriously affecting the safety and use of the bridge pile sex. Different excavation impact on the surrounding environment is not the same, this article analysis the impact on the surrounding environment from the open-cut excavation, reverse dig, semi Reversed three different conditions of deep excavation, concrete content as follows:(1) To learn about the relevant principles of deep excavation under the ground settlement and pile-soil interactions.(2)Based on the measured data of the construction site, the influence of the deep foundation pit excavation on the surrounding ground settlement and the deformation of the diaphragm wall is analyzed.(3) Use the Midas / GTS to simulate actual working conditions of deep excavation,analysis the impact on the surrounding surface subsidence, diaphragm wall deformation and bridge pile settlement, lateral displacement.(4) Comparing actual and simulated done, identify similarities and differences and analyze the causes, guiding construction future...
