| 摘 要： | 山区道路工程在选线时无法避免在边坡上经过,在边坡上修筑路基必然要考虑稳定性问题,但目前对于未见滑面的岩质边坡稳定性尚无统一的计算方法。通过有限元模拟未见滑面岩质边坡的综合分析,其中包括边界条件确定、模拟计算步骤等,最后,通过工程实例的计算分析表明,该方法与重庆市地方规范计算结果相近,具有一定的可行性。 |

| Abstract: | Selection mountain road project can not avoid the slope on the pass on the construction of embankment slope stability must be considered, but subgrade on rock slope without obvious slide surface stability calculation of non-uniform. The finite element simulation no slip surface of the rock slope comprehensive analysis of law, including the boundary conditions, and the steps of simulation calculation. The method of calculation results are close to the results of Chongqing local norms. The method is feasible. |
