边坡荷载作用下的边坡稳定性

分析路基边坡稳定性时考虑的主要因素有边坡的土质、土体的含水率、边坡的几何形状、水的冲刷及地震等,但没有考虑边坡台阶上面的荷载。为了研究边坡台阶上面的荷载对边坡稳定性的影响及影响的程度,采用传统的条分法,通过算例对边坡荷载作用下边坡的稳定性进行了分析,并对比了在无边坡荷载作用下时边坡的稳定性。计算表明:边坡荷载对上边坡的稳定性影响很小,但是使下边坡的稳定性大大低降,从而使边坡的整体功能不能有效的发挥。

Stability of Slope under Effect of Slop Load

Currently,the properties of soil,water content rate of soil,geometry of soil,water erosion and earthquake are considered as the main factors that influence the stability of slop,and the slop load action is not taken into account.In order to study the influence of slope load on the slope stability and the degree of influence,the stability of slop with slop load action and without the slop load action is analyzed using the traditional limit equilibrium method,and then the results of both cases are compared.Through the case studies,the results show that the slop load make little effect on the stability of upper slop,but it will make the stability of underlying slop decrease greatly,so the function of the whole slop is greatly influenced.
