摘要
基于等效连续介质模型 ,应用Taylor展开法分析裂隙岩体渗透性的随机性与裂隙基本几何参数随机性的关系 ,然后用一阶Taylor展开随机有限元法分析裂隙岩体渗流场的随机性。数值分析表明 :隙宽的随机性对渗流场的影响最大 ,裂隙的迹长次之 ,间距的影响最小。
On the basis of the model of equivalent continuous medium, the stochastic relationship of permeability of jointed rock masses with that of basic geometric parameters of joints is first analyzed by usage of Taylor series, then stochastic seepage analysis of jointed rock masses is formulated by stochastic finite element method of first order Taylor series. The numerical results show that the randomness of the width of fissure has a greater effect on seepage field than that of the trace and the spacing of fissure.
