摘    要:本文首次提出裂隙岩体渗流与应力耦合分析的新方法——四自由度全耦合法,该法不仅考虑了裂隙渗透性随应力的变化,而且建立的是同时以渗流水压力和位移为未知值的耦合方程组,使得渗流场与应力场的求解一次性完成.与现有两场交叉迭代分析方法相比,不仅从方法上达到了彻底的完全耦合的目的,而且使得耦合分析变得十分简便,可望有较广阔的应用前景.

关 键 词:渗流  裂隙岩体  耦合分析  有限元法  岩石力学

Abstract:In this paper, a new method called Four-Freedom Complete Method for solving the seepagestress coupled problem in the fissured rock masses is presented. In this method, not only the change of fissure permeability with stress is considered, but also seepage pressure and displacement are taken as unknown variables simultaneously. The new method can overcome the shortcomings of the ordinary method in whioch two fields are alternately iterated, and make the coupled problem become more simple.
Keywords:seepage  stress  fissured rock masses  rock mechanics  finite element method
