Numerical Simulation for Construction Process Large-Span Flat Tunnel under the Condition of Shallow Buried

Abstract:

The thesis takes a three-lane tunnel construction in Zhejiang as an example. Simulating the course of dynamic construction of large-span tunnel on geology condition of four-grade rock mass and shallow buried by FLAC 3D software ,it carries out comparative and stress situation in the runnel surrounding rocks .Getting the displacement and stress changes rule of the construction by using benching with a small pilot tunnel tunneling method can guide the construction scientifically.
