摘要

针对隧道稳定分析计算方法复杂、计算量大等问题，基于滑移线场提出一种简洁方便的图解法具有重要的理论意义和工程意义。首先发展完善了无支护黄土隧道全断面围岩滑移线网络图分析方法，然后，通过MATLAB实现了滑移线网络法的可视化分析程序，结合试验性黄土隧道塌落监测成果验证了无支护黄土隧道全断面围岩滑移线网络图分析方法的分析程序，最后，评价分析了黄土抗剪强度内摩擦角和黏聚力对黄土隧洞围岩坍塌范围及土拱极限承载力的影响。结果表明：黄土土拱极限承载力随黏聚力的增大而增大且敏感程度升高，黄土土拱极限承载力随摩擦角的增大而减小且敏感程度降低，坍塌范围随摩擦角的增大而减小。

Abstract

Based on slip line field to give a simple and convenient graphic method it have great theoretical and engineering significance aiming at the problems of complex calculation method and large amount of calculation in tunnel stability analysis. Firstly

the method of the whole section slip line field at unsupported in loess tunnel was developed and improved. Secondly

the visual analysis program of the slip line network method is realized by MATLAB. Combined with the test results of the experimental loess tunnel collapse

the analysis program of the method of the whole section slip line field at unsupported in loess tunnel was verified. Finally

the influence of the internal friction angle and cohesion of the shear strength of loess on the collapse range of surrounding rock and the ultimate bearing capacity of soil arch in loess tunnel are evaluated.The results show that the ultimate bearing capacity of loess arch increases with the increase of cohesion also the sensitivity. The ultimate bearing capacity of loess arch decreases with the increase of friction angle then the sensitivity decreases

and the sliding range decreases with the increase of friction angle.
