Abstract: Tunnel engineering information construction has been widely used, and the back analysis is its core. As the common useful method, displacement back analysis is of special advantages. This paper introduces the calculative method based on the application in a railway tunnel. The result shows that strain softening model can be used to simulate the large deformation mechanism of surrounding rock.

Abstract: A numerical calculation code FLAC3D is used to simulate excavation of a deep foundation pit of railway station nearby pile group foundations. The horizontal deformations of pile group foundations are then calculated under different operation conditions of excavation, supporting and loading. The influence of foundation excavation to adjacent building is analyzed, which can give some reference to design and construction
