非完整贯通单裂隙渗流研究

摘要

为了分析裂隙内接触面积对渗流的影响，在假设条件及质量守恒原理基础上，建立了非完整贯通单裂隙渗流的数学模型，并针对不同尺寸的接触点情况进行模拟。由模拟结果可知，接触面积的存在对裂隙渗流产生一定的影响，并且在接触面积相同时，单个接触点的尺寸越小，对渗流的影响越大。%In order to analyze the impact of the fractures contact area on seepage,based on assumptions and mass conservation principle,a mathe-matical model of seepage in partial transfixion single fracture was established. And contact points for different sizes were simulated. The numerical results show that the contact area has a certain influence on the fracture seepage and when the contact area is stable,the single contact point is smal-ler,the greater impact on seepage.
