【摘要】 本文分析了软弱夹层对岩体稳定的影响,分析讨论了下列问题,(1)用有限元混合法分析弹性接触问题;(2)研究了软弱结构面的工作状况;(3)地应力场对岩坡稳定的影响。计算结果表明岩体的稳定与地应力条件,结构面产状和强度有关,重点使用作者自编的非线性弹塑性有限元程序分析岩坡稳定问题。在不同地应力水平、不同产状条件下进行岩体失稳过程分析,阐明了各因素间的相互关系。更多还原

【Abstract】 This paper deals with stability analysis of rock mass with weak seams.The following problems are discussed.1) analysis of the three-dimension elastic contact problem by mixed approach using Finite Element Method;2) working feature of the weak seams;3) effection of the ground stress field to the stability of the rock slope. Calculations show the stability of rock mass depends on ground stress condition, the state and strength of structural planes.The nonlinearity plastic-elastic Finite Element Method program made by the author is mainly used in analyzing problem of the rock slope stability.The whole failure procedure of the rock mass with weak seams have been analyzed in the case of different ground stress and different state of the weak structure plane.It gives explanation to the interaction of different factors.更多还原
