路堑边坡稳定性影响因子的均匀设计和数值模拟

将均匀设计引入边坡的稳定性影响因素敏感性分析中，可大大减少试验次数，使试验点在试验范围内均匀分布，得到理想的分析结果。针对杭兰高速公路一典型的路堑边坡，采用均匀设计法，对影响边坡稳定性的7种因素进行了敏感性分析。同时采用有限元数值模拟分析法，针对边坡开挖支护作对比分析，证实了均匀设计的可靠性，得出影响边坡稳定性的因子敏感性由大到小依次为内摩擦角、锚索长度、重度、粘聚力、锚索间距、预应力、锚固段长度，从而为公路路堑边坡的综合治理提供了依据。 

Uniform design and numerical simulation on influential factors of cutting slope stability

The uniform design is introduced into the sensitivity analysis of slope stability,which can greatly reduce the number of trials and make the test points uniformly distributed to obtain satisfactory results.Aimed at a typical cut slope of Hanglan highway,by uniform design,the sensibility of seven factors affecting slope stability was analyzed,on the same time,comparative analysis before and after excavation support was conducted by using analysis of finite element numerical simulation.The analysis confirmed ...
