摘要：
Tunnel excavation disturbed the initial stress balance and caused stress redistribution around tunnel rock. It is significant to research the characteristic of stress and displacement of surrounding rock with or without lining in the process of tunnel excavation. Based on numerical simulation method, this paper studied the distribution and characteristic of stress and deformation around tunnel rock with and without supporting structure during tunnel excavation through large-scale finite element analysis software ABAQUS. The study obtains some useful conclusions which may be helpful for the construction of tunnel. © 2014 ejge.
