在这份报纸，在一个挡土墙后面解决活跃地球压力问题的一个概括限制平衡方法被建议。不同于另外的限制平衡方法，一任意没有预定义的形状的任何假设，滑动表面形状在当前的框架被需要，它被验证发现最可能的失败滑倒表面。基于当前的计算框架，有实验的数字比较，分离元素方法和另外的方法被执行。另外，墙的倾斜的影响，土壤结合，土壤的内部磨擦的角度，土壤的批评压力系数上的装填土壤的斜坡倾斜，结果的地球压力的申请和slip 表面的形状的点小心地也被调查。结果表明那个限制平衡答案从预先规定滑动飞机假设包括库仑答案，是电流的一种特殊情况计算框架。当前的方法是可行的评估地球压力问题的特征，这很好被说明。

英文摘要：

In this paper, a generalized limit equilibrium method of solving the active earth pressure problem behind a retaining wall is proposed. Differing from other limit equilibrium methods, an arbitrary slip surface shape without any assumptions of pre-defined shapes is needed in the current framework, which is verified to find the most probable failure slip surface. Based on the current computational framework, numerical comparisons with experiment, discrete element method and other methods are carried out. In addition, the influences of the inclination of the wall, the soil cohesion, the angle of the internal friction of the soil, the slope inclination of the backfill soil on the critical pressure coefficient of the soil, the point of application of the resultant earth pressure and the shape of the slip surface are also carefully investigated. The results demonstrate that limit equilibrium solution from predefined slip plane assumption, including Coulomb solution, is a special case of current computational framework. It is well illustrated that the current method is feasible to evaluate the characteristics of earth pressure problem.
