边坡失稳是影响高速公路建设进度的主要因素之一,特别是边坡失稳之后岩土力学参数的确定尤为耗时,反演法分析边坡稳定性较好地解决了这个问题。在治理某生态高速公路边坡滑坡过程中,由于所取滑坡体中样本参数悬殊过大,不能获得滑坡面的重要参数,故在该边坡的稳定性计算中,采用反演法获得内聚力和内摩擦角,并对其进行敏感性分析,确定参数的可靠性。然后对边坡进行稳定性验算,实施生态化加固设计方案。
The instability of slope is one of the main factors that affect the progress of expressway construction. Especially the determination of geotechnical parameters is particularly time-consuming after the instability of slope, and the slope stability is well solved by the inversion method. During the process of landslide control of an ecological highway, the important parameters of the landslide can not be obtained due to the large disparity of sample parameters in the landslide. Therefore, in the stability calculation of the slope, the cohesion and Internal friction angle, and its sensitivity analysis to determine the reliability of the parameters. Then the slope stability check, the implementation of ecological reinforcement design.
