摘要
顺层岩质边坡失稳是边坡破坏的主要形式,用力学方法研究其失稳机理是常用手段之一.针对目前该领域研究热点集中在其临界坡长求解方法方面问题,本文利用材料力学方法通过挠曲线近似微分方程求解获得梁的挠曲线方程,进而采用最小能量原理求解和试算法,结合求解顺层岩质边坡的临界坡长.该方法简单适用,对研究顺层岩质边坡失稳机理具有重要意义.
Failure of bedding rock slope is the main type of slope unstability.The mechanical viewpoint is a kind of important means for studying its failure mechanism.The method to solve critical slope length is hotspot in the field.The paper brings forward some viewpoints based on summarizing the before works.Equation of deflection line can be solved by material mechanism,and critical slope length is confirmed with minimizing energy method and dibble dabble.The method is simple and important to studying mechanism of bedding rock slope.
