摘　　要：提出了简单边坡稳定性分析的积分解法,对土条间作用力作了如下假定:认为土条侧面作用力平行于条底,但其大小并不相等。依据平衡条件,结合强度破坏准则,推导了相应于圆弧滑面的力矩平衡和力平衡安全系数积分表达式。以实例进行介绍,并与其它方法进行比较,说明了该方法的合理性。In the paper, a new method is proposed to resolve the stability of soil slopes. The force between the soil spencer is supposed to be parallel to the bottom but does not equal. The integral formulae of the safety factors of moment equilibrium and force equilibrium for circular surface are deduced. Examples show that it is a sensible and effective method of slop stability analysis.
