以库岸边坡路基修建为研究对象,建立库区二维边坡模型,基于Slide软件采用Bishop法和Janbu法对边坡的破坏范围及滑裂面安全系数进行模拟计算,同时建立无水模型对比分析研究水对边坡稳定性的影响。结果表明Janbu法对该模型的计算更接近实际情况,由于边坡地层主要为板岩,滑裂面切割深度较浅,破坏后二次计算显示路基的稳定性满足设计要求。 Taking the construction of subgrade of bank slope as study object, a two-dimensional slope model of reservoir area was established. Based on Slide software, Bishop method and Janbu method were used to simulate the failure range of the slope and the safety factor of slip surface. At the same time, Comparative analysis of the impact of water on the stability of the slope. The results show that the Janbu method is closer to the calculation of the model. Since the slope strata are mainly slate, the cutting depth of the slip surface is shallower. After the failure, the second calculation shows that the stability of the subgrade meets the design requirements.
