| 摘 要： | 采用强度折减法分析了非均质岩体隧洞的稳定性,对比了不同岩层的强度折减对隧洞安全系数的影响。比较结果表明,仅对下层岩体进行强度折减所得的隧洞安全系数最小,仅对上层岩体进行强度折减所得的隧洞安全系数最大,而同时对两层折减(整体折减)所得的隧洞安全系数居中。整体折减所得的隧洞安全系数较符合实际,部分岩体折减方法所得的安全系数不合理。

| Abstract: | A non-homogeneous rock tunnel stability is researched by strength reduction analysis,the effect on safety factor of the tunnel is analyzed by comparing the different rock strength reduction.Reslut shows that safety factor of the upper rock strength reduction only is the biggest than of the overall rock strength reduction,the safety factor of the lower rock strength only is the smallest.Reslut shows that safety factor of the tunnel from the overall reduction is more reasonable. |
