本文主要讲的是极限平衡方法，边坡稳定性分析的极限平衡方法有很多。第一种方法是引入法向基力的新关系。因此，安全系数方程变为非线性。非圆表面失效的简化方法是将潜在滑动质量分成不同的垂直切片。同时介绍了切片的一般过程，从而导致简化方法的发展。在不同的假设下，对层间力作了进一步的贡献。一般极限平衡法是在Morgenstern price法和Spencer法的基础上发展起来的。本篇**代写论文价格**文章由英国论文时Essay Times教育网整理，供大家参考阅读。

Many limit equilibrium methods have been developed for the analysis of the slope stability. The first method was introduced for introducing the new relationships for the normal base force. Thus, the equation of factor of safety became nonlinear. The simplified method for the failure of the non-circular surfaces divided the mass of potential sliding into different vertical slices. The general process of slices was introduced at the same time which leads to the development of the simplified methods. Further contributions were made for interslice forces with different assumptions. The procedure of the general limit equilibrium was developed as the extension of the Morgenstern price and Spencer methods.

All the limit equilibrium methods are based on the assumptions for the shear forces and interslice normal, and the main difference between the methods is based on how the forces are assumed or determined. The equilibrium conditions for estimating the factor of safety and the shape of the slip surface are assumed in this case. The interslice forces rely on many factors which include deformation characteristics of materials and stress-strain. The evaluation becomes more complicated in the presence of limit equilibrium methods. The assumptions are made in the methods either to neglect one or both of them. The forces are considered in most of the advanced methods in the limit equilibrium analysis.

The ordinary method satisfies moment equilibrium for the circular slip surface and neglects both the shear and interslice normal forces. The main advantage of the method is that it examines the factor of safety in a simple way and the equation does not require the interaction process. The factor of safety is based on the moment equilibrium.
