基于ABAQUS的重力坝深层抗滑稳定分析
nti-sliding stability analysis based on ABAQUS software for deep layers of gravity dam
本文归纳了ABAUQS中Drucker-Prager屈服准则的特点。针对平面应变问题，给出了ABAQUS中M-C屈服准则和D-P屈服准则抗剪参数的转换公式。总结了坝体-地基系统的失稳判据。然后结合弹塑性有限元分析的相关理论，利用强度储备法和失稳判据，运用ABAQUS有限元分析软件，对复杂地质条件下某重力坝进行深层抗滑稳定分析，给出了该坝段的深层抗滑稳定安全系数以及坝体的滑移模式。
In this paper the characteristics of Drucker-Prager rule in ABAQUS were concluded. Based on plane-strain problem, the formula for translating M-C parameters to D-P parameters in ABAQUS software was given. The criterions of sliding stability of gravity dam were summed up in this paper. Then the anti-sliding stability of a gravity dam with complicated geological condition was analyzed by use of theories of elastic-plastic FEM, strength decreasing algorithm, criterions of sliding stability and ABAQUS software. Furthermore the integral stability degree and the slid mode of the dam were given.
