应用ABAQUS软件结合强度折减法分析边坡稳定性

摘要

针对边坡稳定分析中采用的材料参数强度折减法，采用基于ABAQUS场变量来控制强度参数的折减。通过实际工程算例分析，并与采用极限平衡法进行对比。结果表明：采用塑性区的贯通和最大位移突变作为极限状态判据所得到的安全系数是合理可靠的。%According to the material strength reduction method used in slope stability analysis, this paper deals with strength reduction controllingbased on ABAQUS field driving. Through the actual engineering example analysis, the limit equilibrium is compared. It shows that the judgment of plastic zone breakthrough and displacement mutation as criterion for stability is reasonable and reliable.
