边坡潜在滑动面抗剪强度参数的合理确定是对边坡进行有效治理的前提条件。为了准确地确定边坡潜在滑动面抗剪强度参数,通过分析边坡现状的稳定性及边界条件,确定其边坡现状的安全系数。在边坡岩体c、φ值对安全系数变化的影响进行敏感性计算的基础上,结合边坡岩体抗剪强度参数试验推荐值反演了与边坡现状条件相对应的岩体抗剪强度参数的合理值。研究成果表明该反演方法在工程上具有较高的可靠性。
The reasonable determination of the potential sliding surface shear strength parameters of slopes is a prerequisite for the effective control of the slope. In order to accurately determine the potential sliding surface shear strength parameters of the slope, by analyzing the stability of the status of the slope and the boundary conditions, to determine the safety factor of the status quo of the slope. On the basis of the sensitivity calculation of the influence of c, φ value on the safety factor of slope rock mass, the shear strength of rock mass corresponding to the status quo of slope is deduced based on the recommended values of shear strength parameters of slope rock mass Reasonable value of the intensity parameter. The research results show that the inversion method has high reliability in engineering.
