Abstract: Based on the effect and analysis of sensitive building on design of deep foundation pit bottom-fastening of soft soils inside Ningbo subway line l Ximenkou metro station, the data processing method was adopt design. Utilizing the deformation of supporting structure which was obtained from the model of finite element simulation of a PLAXIS 2D 8.X and FLAC3D3.0 under complicated geological conditions. As the experimental marriage Partner, and basing on the appropriate level of the factor figure, we select the suitable orthogonal array to carry on the numerical simulation experiment. According to the Range analysis, variance analysis and the analysis of Contribute effect picture, among the greatest factor which influence the displacement of supporting structure. Parameter sensitiveness which was from great to light arranges were summarized and could be reference for design and construction of similar projects.
