By using positive plasticity collision principle and functional equation, a new functional equation is set up between the gliding object and barricade, a formula deduced calculating the weight of barricade, from which the thrust and counter-slide force of landslide can be worked out, finally an overall stability coefficient, taken as the only numerical value, derived.
用塑性正碰撞原理和功能方程,建立滑移体与挡墙(或锚杆档墙)关系的功能方程,导出计算挡墙重量(或锚杆挡墙重量)公式,由此重量计算滑坡推力和抗滑力,获取整体稳定安全系数,该系数是唯一值。
