摘要
基于ABAQUS软件在岩土分析计算中的应用,采用强度折减法讨论了忽略剪胀角的均质边坡和考虑软弱夹下卧层二种工况下某边坡的安全系数。结果表明:随着折减系数的不断增大并达到某一数值时,边坡内塑性应变自坡底向坡顶贯通,边坡达到极限状态,此时的折减系数即为安全系数;有限元强度折减法对边坡稳定性分析具有良好的适用性;采用强度折减法无须预先假设滑动面位置。
Based on the great geotecl＇aical analyzing function of A, through streng reduction fern, cussing tile safe factar of the slope under dllatancy ignored uniform slope angle and consider the weak two folder LaCier the underlying layer. The reJ showed that： VCrh the increasing efficiency factor and aclieve a value, the slope of he plastic strain from its base to the top of the Ill through the slope to reach thestat, when the reduction factor is the safety factor;Lirri＇td stg reductin of the slope stablly has a good al：lf, EalIgy; The ssurface Iocatbn should not be strength reduction fern.
