Introduction It is generally acknowledged that the excavation procedure is a key problem in tunnel engineering especially for the fracture rock-mass and worse geological condition.
Computation Model Flac3D is a numerical analysis method with three dimensional displaying and it is widely used in the assessment of slope stability, supporting and construction design, evaluation of underground caverns, arch dam stability analysis, tunnel and mining engineering.[5-6] In this paper, the numerical model is established according to a typical constructing geological section of which 28254 nodes and 23240elements in the dimension is of 30m×3 m×30m(length×width×height).
