摘要
本文根据有限单元法和刚体极限平衡原理,探讨了岩质高边坡稳定分析新途径。在分析已有的参数反演原理基础上,进一步完善了参数反演原理,提出了新的参数反算方法.同时,文中阐述了三维弹塑性有限元变“Kp”迭代法解题原理,在有限元计算成果的基础上,探讨并提出了计算稳定安全系数的新方法.
In this paper,new stability analysis methods of high rock slope is sought, mainly on the basis of FEM and limit equilibrium principle of rigid body. On the basis of the back-calculation principles having been snggested,a new one is snggested and the back calculation theories are enriched and improved. The principle of the interactive algorithm of small increment changeable-kp is introduced which solves the problems of FEM.New methods that calculate stability factor are suggusted and searched for.
