摘要

以平面有限元位移法分析了带裂纹隧道二次衬砌裂纹尖端的应力强度因子及衬砌承载安全系数，其中主要考虑了裂纹深度、宽度及条数的影响。从计算结果得知，随着裂纹深度、条数的增加，应力强度因子增大，衬砌承载安全系数减小，而裂纹宽度的影响不太明显。

Abstract

The authors analyze the stress intensity factors at the tips of cracks in a tunnel lining and the safety factors for bearing capacity of the tunnel lining by using a 2D FEM code

in which the influences of lengths

widths and number of cracks are mainly considered. The computation results show that the stress intensity factors raise and the safety factors of bearing capacity decrease with the increase of lengths and number of cracks

but the effect of crack widths is not so obvious.
