摘要：
ABAQUS finite element analysis software and load - structure method are adapted in this paper and the structure is simplified as a two-dimensional plane model. 25 kinds of working condition including five hole sizes: 0.6m, 1.2m, 1.5m, 1.8m, 2.1m and five hole positions varying from vault to arch springing are studied and the safety factor distribution of lining are obtained. By comparing the safety factor at dangerous section in lining with hole to that in no damage lining, a convenient evaluation method about the effect of hole to lining safety is proposed.
