Under the situation of urban traffic congestion, subway has become the advantageous improved tool of the urban transport situation .As the city is updated constantly, if super-tall structures are built near the lines of the subway, neighboring subway structures will be affected by the process of building foundation construction. The soil around can be made to take a certain effect on subway section and its segment of deformation whether in the early stage of the retaining piles construction or the late foundation piles construction. Too large deformation will make subway tunnel accidents. So it is necessary for the research that action of deep excavation construction process for nearby subway section. We will have more and more cities with subway in future. New building construction will often encountered such problems in crowded cities. Moreover now it is very keen on the research that action of deep excavation construction process for nearby subway section in domestic, so the research on this problem will bring a lot of help study for the future urban construction in China.The research topic is a existing subway section on the west side10 meters of the building site which has a planning super-tall building in Shenyang. The research content mainly includes effect and action of super-tall structures deep excavation construction process for the neighboring subway section. The paper used the method of numerical simulation, firstly, collecting and sorting some data, then select the ’structural and calculation parameters through preliminary calculation and research. By using the ANSYS finite element analysis software, three-dimensional finite element analysis has modeled for deep excavation construction process and subway section. I n the end, based on the fact survey date about the subway section of Shenyang Henglong square, a comparative analysis of the influence of deep excavation construction process for nearby subway section, all sorts of deep excavation infection curves are also given. Action is identified in different subway section construction methods, so as to give suggestions and references for similar construction in future.
