针对强度折减法的计算结果可能影响工程设计人员对土坡稳定程度的合理判定的问题,以某均质土坡为例,基于PLAXIS数值分析软件,分析了有限元网格疏密程度和边界条件对强度折减法计算结果的影响,通过与简化Bishop法计算结果的对比,建议了合理的网格疏密度和边界范围取值,并基于不同取值的岩土物理力学参数,验证了强度折减法计算结果的合理性。
The calculation results of the strength reduction method may affect the reasonable judgment of engineering designers on the stability of soil slopes. Taking a homogeneous soil slope as an example, based on PLAXIS numerical analysis software, the degree of finite element mesh density and the boundary conditions Based on the comparison with the simplified Bishop method, a reasonable grid density and the range of the boundary are proposed. Based on the different physical and mechanical parameters, the strength reduction method is validated Calculate the rationality of the result.
