| 摘 要： | 裂隙中水流为紊流状态时，流量与水力坡度呈非线性关系，不再满足线性的立方定律，以岩体裂隙网络中结点的水量平衡来建立岩体裂缝网络非线性渗流控制方程式，提出矩阵求解方法和迭代运算步骤，并给出应用算例与验证。算例结果表明，不能采用岩体裂隙网络线性渗流规律来代替岩体裂隙网络非线性渗流规律。

| Abstract: | The flow rate is nonlinearly related to the hydraulic gradient when fluid flow through the fracture network in rock mass is turbulence. The governing equations for seepage through fracture network in rock mass were establised based on water balance at nodes, and the matrix solution method and the iterative steps were proposed. An example was also given to show that the law for seepage through fracture network in rock mass cannot be approximately regarded as the linear one. |
