The numerical simulation and Deformation analysis to the deep foundation pit of diaphragm wall based on Midas/GTS

摘要

Taking the J2 area YK10+615～YK10+650 miles section related to the connection line of River-crossing tunnel to Nanjing plum delta--the youth Olympic axis underground traffic system engineering as the background, the 3d model is established by using finite element software MIDAS/GTS, the mileage period of excavation process is simulated, discuss the influence of excavation on adjacent soils. Calculation results show that the excavation will inevitably cause deformation of adjacent soil, and comparing the results of calculate and the actual monitoring data show that the method has certain guiding significance to actual engineering.
