针对任意形状的二维滑面边坡,选取滑体中任意单元体为研究对象,通过垂直于合外力方向上的静力平衡关系求解滑面上的剪应力;参照矢量和法定义安全系数的方式,求解出滑体下滑趋势方向,沿此方向求得边坡安全系数。通过与经典算例验证表明:该方法得出的边坡安全系数与其它方法计算结果基本一致,验证本文方法是可行的,可应用于边坡稳定性分析,且表明滑面上的剪应力分布状态对边坡安全系数是有影响的。 For arbitrary shape of two-dimensional sliding surface slope, the arbitrary element in the sliding body is selected as the research object, and the shear stress on the sliding surface is solved by the static equilibrium relationship perpendicular to the direction of the external force. The safety factor Way to solve the direction of sliding body slip trend along the direction of slope safety factor. The results of classical numerical examples show that the slope safety factor obtained by this method is basically the same as that of other methods. It is feasible to validate the proposed method and can be applied to slope stability analysis and show that the shear stress distribution on slip surface The state of the slope safety factor is influential.
