摘    要:有限元重度增加法通过增大自重直至边坡破坏,此时重力增大的倍数即为安全系数,具有概念清晰、操作简便等优点。但在缓坡和内摩擦角较大时所得安全系数偏大,从而阻碍了该法的发展。文章提出修正的重度增加法,通过算例与简化B ishop法和强度折减法相较,以及在黑泉水库岩质边坡稳定中的应用,结果表明:修正的有限元重度增加法,在粘性土和岩质边坡稳定中的应用是切实可行的。

关 键 词:有限元重度增加法    边坡稳定分析    安全系数    ADINA

Abstract:Gravity increase finite element method is to increase deadweight until slope destruction,where the multiple of gravity is the safety factor,which has the advantages of clear concept and simple operation.But safety factor is greater in gradual slope and with larger internal frictional angle,which obstructs the development of this method.This paper advances corrective gravity increase method.Through comparison with simplified Bishop method and strength reduction method as well as the application in rock slope...
Keywords:gravity increase finite element method  slope stability analysis  safety factor  ADINA
