摘要
某高速公路的边坡工程由于连续降雨的作用,出现边坡失稳产生了变形体破坏。以此工程为背景归纳了由于边坡失稳而导致变形破坏的基本特征;对暴雨情况下变形体滑面抗剪强度参数进行反演;根据反演的参数对各典型剖面进行稳定性验算,得到了在雨季工况下的稳定性系数及剩余下滑力。结合现场变形特征与理论计算对边坡的稳定性进行了评价,并提出了相应的综合治理方案。
A highway slope engineering due to the role of continuous rainfall,appear the slope unstability deformation damage.In this paper,according to the engineering background summarizes the basic due to instability of slope deformation and destruction features;For heavy rain cases plasmodium sliding surface shear strength parameters inversion;According to the inversion of the parameters for stability calculation of the typical profile,the stability coefficient under the condition of in the rainy season and residual slide force.In combination with the deformation characteristics and the theoretical calculation on the slope stability is evaluated,and proposed the corresponding comprehensive control scheme.
