不同堆积角度对松散堆积体稳定性影响模拟分析

Simulation analysis on the stability of loose accumulation masses effected by different stacking angle

以碎石土为例,运用有限元ANSYS软件模拟碎石土的堆积角度,采用工程中应用较多的强度折减法研究了不同堆积角度对松散堆积体稳定性的影响,讨论了堆积体位移,应变和应力的变化规律,并拟合分析了安全系数与堆积角度的关系,以供参考。

In this paper,grave soil being an example,by applying finite element ANSYS software to simulate the stacking angle of gravel soil and adopting strength reduction method widely-used in engineering to explore the effect on stability by loose accumulation masses in terms of the different stacking angle,it discusses the changes of displacement,strain and stress of accumulation body as well as fitting and analyses of the relation between safety coefficient and stacking angle,with a view to provide some reference.
