摘要
安全系数是边坡稳定判别的重要标准,能精准、快速地获得相应的安全系数,一直是边坡稳定性分析的重点。基于FLAC3D计算软件,将最小二乘法与强度折减法相结合,建立了安全系数与边坡物理力学参数的非线性关系,提出了一种快速获得边坡安全系数的搜索方法,并对其进行了验证。
Safety coefficient is an important standard of slope stability criterion, which is always the key point of the slope stability analysis to get the corresponding safety coefficient accurately and quickly. This paper establishes the nonlinear relationship of safety coefficient and physical and mechanical parameters of side slope by combining with least square method and strength reduction method and basing on FLAC3D calculation software. It also proposes a fast search method to get the slope safety coefficient and carries verification about it.
