基于ABAQUS有限元模型的边坡变形破坏规律研究

Law Research of Finite Element Slope's Deformation and Failure Based on ABAQUS Model

边坡变形破坏规律的研究一直是我国地灾防治工作者的重要课题.影响边坡变形破坏的因素有很多,对边坡的坡高、坡角、摩擦角及粘聚力4个影响因素进行研究分析.首先验算了ABAQUS模拟计算均质土边坡的稳定安全系数的合理性,然后针对4种主要影响因素采用单值变化的方法研究分析边坡变形破坏的规律,得出的破坏规律与我们在经验中获得的规律一致.

The law research of slope deformation and failure in China has always been a key research item of workers＇ who work on disaster prevention and control. There are many factors impacting slope deforma- tion and failure, in which slope height, slope angle, friction angle and cohesive strength were researched in this paper. The rationality of safety coefficient of homogeneous soil slope caculated by ABAQUS simulation was checked. For the main four impacting factors, slope deformation and failure law was studied by method of single value change. The findings indicate that the law obtained by the method is consistent with the law obtained by experience.
