明确裂隙间的相交关系,去除那些对流体流动与溶质运移无贡献的、与其他裂隙不联通的裂隙,能够大大提高裂隙中流体流动和溶质运移数值模拟的效率.提出一种基于空间索引的随机分布三维裂隙网络中裂隙对逐步相交判断的方法.通过数值模拟试验比较了该方法与传统的穷举法,结果表明,该方法速度快、成本低,大大减少了裂隙岩体渗流计算量,缩短了裂隙岩体流体渗流和溶质运移数值模拟计算时间.
It is clear that the relationship between fractures is clear and the fractures which do not contribute to fluid flow and solute transport and are not in communication with other fractures can be removed and the efficiency of numerical simulation of fluid flow and solute transport in fractures can be greatly improved. The method of judging the gradual intersection of fractures in the three-dimensional crack network with random distribution is proposed.The numerical simulation test compares the method with the traditional exhaustive method, and the results show that the method is fast, low cost and greatly reduces the calculation of seepage of fractured rock mass , Which shortens the time of numerical simulation of fluid seepage and solute transport in fractured rock mass.
