| 摘 要： | 推导了坡面为两直线段斜坡的均质边坡稳定性安全系数函数式,利用遗传算法求出最危险滑弧位置、滑弧半径及相应的最小稳定性安全系数值,利用有限元法和接触摩擦弹簧元进行了边坡的渐进破坏分析,讨论了材料特性对边坡稳定性的影响。计算表明,渐进破坏分析所求出的稳定性安全系数比理论上求出的最小稳定性安全系数要小。

| Abstract: | The function expression about safety factor of homogeneous slop stability is deduced, and the slop surface is consist of two lines and an arc. Genetic algorithm is applied to solve the most dangerous situation, radius of the sliding surface and corresponding minimum safety factor of slop stability. Finite Element Method and Spring Element Method of contact friction are applied to analyze the progressive failure process of the slop, and the effect of material characteristics on the slop stability is discussed. The calculated results show that the safety factor of slop stability calculated by considering progressive failure is less than that obtained by common theory. |
