摘　　要：本文从能量的观点出发推导出了重力滑坡体和地震滑坡体在固定边界条件下滑动轨迹的欧拉方程。然后由变分原理求解该方程,得到滑体的滑动轨迹。最后以世界罕见的洒勒山大滑坡为例,验证了该方法,计算滑面与实际滑面基本平行。该方法的提出对于滑坡过后寻找滑面时钻孔孔位的布置、钻孔数量的确定、滑坡稳定性计算时的滑面形状的确定以及滑动液化的评价都具有指导性的意义。In this paper, at first, based on the view of conservation of energy, we calculated the Eulor's Equation of sliding locus of gravity and earthquake landslide masses under the fixed boundary condition. Next, this equation is solved by variational calculus method. Finally, We verify this method by Saleshan Landslide being famous which is so big that is rarely seen through the whole world. Then comparing the results with the practical sliding path curve, it shows that their identical degree is very spectacular. This rescarch is of important referential value to the location and number of drill holes and evaluation of saturated soil liquefaction reasoned by landside.
