摘　　要：渗流场与应力场的分布对矿体和巷道的结构稳定有重要的影响。利用ANSYS热分析功能来比拟渗流场,分析了矿体和巷道的渗流场与应力场分布。模拟结果表明,矿体考虑了渗流场的影响后,应力场有所增加。巷道最大应力区域出现在巷道两侧,得出巷道的破坏往往最先发生在巷道的两个肩与两底角的结论。Distribution of seepage field and stress field of orebody and tunnel were analyzed by using thermal analysis module of ANSYS to compare seepage field.The numerical results show that the values of stress field would increase if the effect of seepage field was considered for ores;for the tunnel.The maximum stress regions appeared on the both sides of the tunnel.So the failure of tunnel often occurs in the two shoulders and two bottom corners of the tunnel at the beginning.
