摘要

如何引用项目王，中，林，M（2021）。基于模糊统计的边坡稳定性有限元分析方法。《地球科学研究杂志》，25（1），123-130。DOI：https://doi.org/10.15446/esrj.v25n1.93320为了降低由于计算参数的模糊性而导致的边坡稳定性评价风险，提出了一种基于模糊统计的边坡稳定性有限元分析方法。基于准静态方法的原理，借助有限元软件COMSOL multiphysics，研究了不同地震加速度作用下砾石土堆积岩质边坡的稳定性。通过分析岩土边坡的位移、塑性区和安全系数，对岩土边坡进行了稳定性分析。研究结果表明，岩土边坡力学参数的模糊性会导致岩土边坡位置位移和应力分析结果的模糊性，采用模糊有限元分析方法对岩土边坡进行分析可以加强对位置位移的全面认识，工程技术人员对岩土边坡的应力和安全性进行了研究，并在一定程度上由于计算参数的模糊性而降低了岩土边坡稳定性。基于模糊统计的边坡稳定性有限元分析方法
