| 摘 要： | 针对高陡路堑边坡设计一般只简单采用极限平衡法进行成型边坡稳定性验算的现状,以广贺高速公路高陡路堑边坡为工程背景,采用数值分析方法对高速公路高陡路堑边坡施工开挖过程进行了模拟,对比分析了不支护与及时支护开挖过程的边坡稳定性,指出了开挖过程的危险阶段,分析了及时支护的效果与必要性,提出了施工优化步骤。结果表明:有限元计算可以实现边坡分层开挖分层加固施工工序的优化设计,锚固支护有效改善了边坡体受力状态与临界塑性应变特征。

| Abstract: | As result of the current status about the high steep slope using a simple design of the general limit equilibrium method for slope stability evaluation,one means of numerical simulation is used to analyze the slope's stability of the high steep highway cut slope during the excavation process,taking the high steep slope of Guang-He Highway as engineering background.First,the slope stability that excavated without support and excavated with supporting timely is compared to analyze.Second,the danger constructi... |
