当λ= 0时,安全系数得到房子和BSM。相交点表示M-PM或SM的安全系数。广义杨布方法接近交点。广义极限平衡过程具有在同一图中比较安全系数的优点。该程序可用于复合材料和圆形材料的稳定性分析。变量层间力函数描述了层间力在后续迭代后的倾角。

广义极限平衡同时考虑剪切力和层间力,满足力平衡和力矩平衡,允许层间力函数的选择,并描述了最先进和常用的极限平衡方法的比较。OM是手工计算的。JSM砂- BS广泛用于稳定性分析。这些方法很常见,因为在大多数情况下,一个安全系数可以用足够的精度来估计。这些方法在满足力矩和力平衡方面有一定的局限性。采用BSM法对圆形剪切面进行了分析。

JSM在检测非圆表面的安全系数方面是灵活的。JGM的优点可以有效地处理破坏面和不规则边坡。切片的力矩平衡给出了接近安全系数的力平衡解。与JSM相比,BSM的安全系数更高,下降幅度在严格方法得出的安全系数的5%以内。与Morgenstern-Price和Spencer方法计算的结果相比,安全系数可以相差15%。

从力矩平衡可以看出,力平衡的安全系数对f(x)更敏感。安全系数对f(x)的截面很敏感。在锚或点荷载的情况下,弯矩平衡安全系数有相当大的向较低的安全系数偏移。在应用外力时,考虑力矩平衡的安全系数更为敏感。由于锚固力或点荷载的作用,层间剪切力增大。降低了正态地基力,降低了抗剪强度。

When λ= 0, the factor of safety is obtained for JSM and BSM. The intersection point shows the factor of safety for M-PM or SM. The Janbu’s generalized method is close to the intersection point. The generalized limit equilibrium processes have the advantage to make comparisons of a factor of safety in the same diagram. The stability analysis for composite and circular SS can be used in the procedure. The variable interslice force function describes the inclination of interslice forces after the subsequent iterations.
The generalized limit equilibrium considers both shear and interslice forces, satisfies both force and moment equilibriums, allows selection for the interslice force function and depicts the comparison of most advanced and common limit equilibrium methods.The OM is calculated by hand. JSM sand BS have used widely for the stability analysis. The methods are common because in most cases, a factor of safety can be estimated with the adequate accuracy. The methods have some limitations in the satisfying moment and force equilibrium. The BSM is used for the analysis of circular shear surface.

The JSM is flexible in examining the factor of safety for the non-circular surfaces. The advantage of JGM can be handled effectively at both failure surfaces and irregular slopes. The moment equilibrium for the slices shows the solution for the force equilibrium which is close to the factor of safety.The BSM shows a higher factor of safety than JSM and declines within 5% of the factor of safety obtained from rigorous methods. The factor of safety can differ by 15% in comparison to the results calculated by Morgenstern-Price and Spencer methods.
The factor of safety from force equilibrium can be seen more sensitive to the f(x) from moment equilibrium. The factor of safety is sensitive to the section of f(x).In the case of the anchors or point loads, the moment equilibrium factor of safety has considerable shifting towards the lower factor of safety. The factor of safety from the moment equilibrium is considered as more sensitive in the application of the external forces. The interslice shear forces increase due to the anchor forces or point loads. It can decrease the normal base force, and the shear strength is decreased.
