摘要

摘要: 为研究锚固加强对边坡稳定性的影响，基于边坡稳定性分析的整体方法，将锚固力简化为坡面上的集中力，基于锚固力由整个滑坡体而不是单个条块承担的假定，导出了锚固边坡安全系数的计算式。由于整体分析法以整个滑坡体而非极限平衡条分法中的条块为研究对象，通过整体的三力矩平衡方程代替传统的水平、竖向力平衡及力矩平衡方程的形式，使所得到的方程数值特性更好，边坡的内力更为光滑并且适用于各种形式的滑动面。最后通过三个典型算例验证该方法的有效性。

Abstract: Based on the global method of stability analysis for stopes, a method to consider the effect of anchor reinforcement on slope stability was proposed, in which anchoring forces were assumed to be borne by the whole sliding body instead of individual slices as a concentrated force,the formula for safety factors of anchored slopes was deduced. As the equilibrium conditions were formulated in terms of the whole slip body instead of individual slices, the internal forces in slopes were more authentic. Simultaneously, three equilibrium equations for moment were formulated according to the global moment equilibrium conditions rather than the traditional equilibrium equations for forces in horizontal and vertical directions and one moment equilibrium equation. Therefore, the method was not only suitable for slopes with slide surfaces with different shapes,but also possessed more excellent numerical properties. Finally,three classical examples were given to prove the effectiveness of the method.
