Design And Numercial Simulation Of Supporting Structure Of Excavation In Wulihe

With the development and utilization of underground space in the city and the construction of high-rise buildings, deep excavation engineering become more and more. Because the most of the deep excavation engineering in city are all in the dense buildings, limited and narrow construction site conditions,the deformation of excavation construction on the demand is higher,the requirement of foundation pit design is becoming more and more high.Present calculation mainly adopts the principle foundation pit supporting is a series of deep foundation pit software,displacement, there is still a gap between calculation and experimental data, this paper is software calculation, the actual displacement observation and the Midas GTS software simulation, discusses some problems in the design of foundation pit.In this paper, based on a hotel in Shenyang the excavation project of Wulihe, the excavation design adopted the bored piles with prestressed anchor excavation supporting structure.Supporting structure design USES reason is deep foundation pit software, the wall displacement of excavation supporting the whole construction process of the actual measurement,this design of excavation and simulation are carried out using the finite element software Midas/GTS.Based on the actual measurement verification feasible software model, the simulation for the design of foundation pit supporting structure, some conclusions are obtained.This article through to the project calculation, measurement and finite element numerical simulation analysis, the conclusions on the supporting design of foundation pit engineering is similar and complex foundation pit supporting project has a certain reference significance.
