Structure optimization design based on the numerical simulation of subway station deep foundation in open cut

摘要

In the subway station deep excavation in open cut, there are many factors affecting its envelope stability for engineering geology and environmental variability. Now, taking Zhengzhou line 2 subway station foundation pit engineering as an example, taking measures monitors the horizontal displacement of retaining piles for deep foundation pits around the retaining structure stability retaining structure, at the same time uses different softwares for numerical simulation. First, in the same location, the datum from the different softwares and construction monitoring are compared. Then, as the project safe, feasible and economy under the premise, the structural optimization design is put forward. Namely, the date obtained software simulation and the corresponding are compared in different position of the inner support measured. Last, the analysis of the retaining structural deformation law and the impact on the structural stability of deep foundation pit in the different support position are necessary, so that the design has been optimized.
