摘要
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。
Side slop losing stability is one of the main factors which greatly influences expressway ex- pedite construction, especially after side slop losing stability, the determination of rock and soil mechanics parameter may take a long time. Inversion method to analyze slope stability can preferably solve the prob- lem. During the treatment of the ecological expressway landslide, the important parameters can not be ob- tained due to great disparity of sample parameters of landslide. However, using inversion method to get cohesion and internal friction angle, and anglicizing its sensitivity during calculation of stability can identify reliable parameters. According to slope stability calculus, the ecological reinforcement design scheme come into effect.
