| 摘 要： | 提出了一种边坡稳定分析的三维极限平衡法.该法满足每个条柱3个正交坐标轴方向上的静力平衡,同时也满足整体绕平行于坡面纵轴的转轴的力矩平衡.分析了条柱侧面平均剪力和条柱总数对边坡安全系数的影响.结果表明,条柱侧面平均剪力对安全系数有一定的影响,当采用简化Janbu法时尤其如此.通过算例和已有的几种方法进行了比较分析,验证了该三维极限平衡法的合理性.

| Abstract: | This paper described a three-dimensional limit equilibrium method for slope stability analysis.This method makes sure that each discrete column satisfies the force equilibrium in all the three directions and the slide mass satisfies the moment equilibrium against the axis of rotation which parallels the y axis.The paper analyzed the affection of the average inter-column shear force and the total number of the discrete columns on the factor of safety.The study demonstrates that the average inter-column shear force has influence on the factor of safety,especially when using simplified Janbu's method.The results of the examples with other limit equilibrium methods were also compared. |
