摘要 采用一种侧向加载模型箱,开展了隧道位于黄土中(工况1)和隧道被黄土中潜在滑动面贯穿(工况2)两种工况的模型试验,研究了边坡变形过程中隧道衬砌的受力特性,分析了坡体变形、隧道围岩压力变化以及衬砌弯矩变化等规律。结果表明:两种工况下隧道衬砌临近坡面一侧附近围岩均易形成脱空区,工况1脱空区最大宽度约为1 cm,工况2约为2 cm,工况2中脱空区远大于工况1,相对增幅达到100%;工况2衬砌弯矩峰值相较于工况1增幅明显,相对增幅为159.33%,最大增幅位于临近坡面侧拱脚区域,边坡中潜在滑动面的滑动显著增大了隧道衬砌破坏的可能性。

Abstract: A lateral loading model box was used to carry out model tests under two cases: the tunnel was located in loess(case 1)and penetrated by potential sliding surface in loess(case 2). The stress characteristics of tunnel lining in the process of slope deformation were studied, and the laws of slope deformation, pressure change of tunnel surrounding rock and lining moment change were analyzed. Results showed that the surrounding rock near the slope side of the tunnel lining was easy to form a void zone under the two cases. The maximum width of the void zone was about 1 cm in case 1 and close to 2 cm in case 2. The void zone in case 2 was much larger than that in case 1, with a relative increase of 100%; Compared with case 1, the peak value of lining bending moment in case 2 increased significantly, with a relative increase of 159.33%, and the maximum increase was located in the area near the side arch foot of the slope. The slide of the potential sliding surface in the slope significantly increased the possibility of tunnel lining damage.
Key words:  bearing characteristic    potential sliding surface    tunnel lining    void zone    model test
