针对裂隙岩体渗流非均质各向异性的特点,我们用基于离散连续模型(discrete continuum model,简称DC模型)的方法,对裂隙岩体渗流和溶质运移进行了数值模拟。在此工作中我们采用Oda裂隙张量理论计算各个单元的渗透张量,组成整个渗流区域的渗透张量场;并采用具有“旋转不变性”特征的九点差分格式,来减少网格离散方式对数值模拟结果的影响;并对一benchmark test model(BTM)模型进行了数值模拟。模拟结果与BTM结果很吻合。 According to the anisotropy of seepage in fractured rock mass, we use the method of discrete continuum model (DC model) to simulate the seepage and solute transport of fractured rock mass. In this work, we use the Oda fracture tensor theory to calculate the infiltration tensor of each element and make up the infiltration tensor field of the whole seepage region. The nine-point difference scheme with the feature of “rotation invariance ” is used to reduce the grid Discrete mode on the numerical simulation results; and a benchmark test model (BTM) model for numerical simulation. The simulation results are in good agreement with the BTM results.
