| 摘 要： | 在宝(鸡)-兰(州)复线东巨寺沟硬岩铁路隧道拱顶位移和位移收敛测试数据的基础上,采用有限元法对该隧道围岩的构造应力进行数值反演,利用地应力反演结果对隧道围岩稳定性进行了分析和评价.采用反演的地应力分析结果表明,拱顶下沉、水平位移收敛值与实测值接近,支护结构围岩处于稳定状态.

| Abstract: | The finite element method is used to inversely determine the Dongjusi railway tunnel rock mass initial stress field combined with the tunnel crown displacement and horizontal displacement-convergence measured results. The railway tunnel rock mass stability is analyzed using the inverse analysis results. The numerical inverse analysis result shows that the calculated arch crown displacement and the horizontal displacement convergence results eonincides with those of the measured results. The lining structure and the rock mass is in stable state. |
