摘要:
边坡的潜在滑裂面可能不通过坡趾,而是在坡面上某点发生了局部剪切破坏。研究条形荷载作用下边坡的滑裂面位置及其稳定性判识方法,应用M-C线性破坏准则结合极限分析上限定理,建立稳定性系数与多变量的函数,将相关问题转化为含有多变量的数学优化问题并给出最优解。结果表明:边坡的潜在破裂面、稳定性与边坡几何形状、土体物理力学性质、荷载特性等因素有关。
Abstract:
Potential sliding surface may not be through the slope toe, but it can be through the point of slope surface. In this paper, a new approach that potential sliding surface position and slope stability are studied, and the formula is deduced with the M-C failure criterion combining upper bound method. We introduce variables and the slope stability turns into a mathematical optimization problem which contains multiple variables and we find the optimal solution. The numerical results show that slope safety factors are related to the slope shape and the properties of soil and the strip load. Potential sliding surface position is relevant to the slope shape and the strip load and the internal friction angle, but it is not relevant to cohesion.
