Bishop法滑坡稳定性分析及滑坡治理

Bishop Method for Stability Analysis and Landslide Control

采用有限元Bishop法定量评价公路边坡的稳定性,依据勘察资料建立分析计算模型,分析在天然状态下土壤特性,获得物理参数,并建立多个坡段,选择多个坡面节点和附加节点,进而提高建立模型的准确度。通过运算定量获得边坡的稳定性系数,并获得在降雨和地震情况下的稳定性,为定量分析边坡稳定性提供了参考依据,并为治理措施的选择提供了针对性较强的量化依据。

Taking finite element Bishop method to evaluate the highway slope stability quantificationally, to set up the analytic model based on the investigation data. Analysis soil properties in natural condition, obtain the physical parameters, and establish multiple slope section, select multiple slope node and additional nodes, so as to improve the accuracy of model. The stability factor of the slope is obtained quantificationally through calculation, meanwhile, the stability of the slope is obtained under the conditions of rainfall and earthquake, which provide a reference basis for quantitative analysis of the slope stability, and to provide a strong basis for the choice of governance measures.
