| Abstract | 为解决裂隙岩体非稳态渗流问题，发展了一种新的数值模型。对于单裂隙渗流求解，其控制方程是基于一定假设的简化Navier-Stokes方程，数值方法采用有限差分法和流体体积法。在裂隙网络中，交界处渗流可以由专门的控制方程求解。计算结果表明，该数值模型既可以大幅提高非稳态渗流的计算效率，还可以避免孤立裂隙所带来的影响。最后，通过两个工程算例验证该数值模型的适用性 |
| Other Abstract | In order to solve the problem of unsteady fluid flow in fractured rock,a new numerical model is proposed.For the calculation of fluid flow in a single fracture,the governing equations are simplified Navier-Stokes equations based on some assumptions,which are numerically solved by the finite difference method and the volume of fluid method.In a fracture network,the fluid flow in intersection places is governed by special equations.The results show that this numerical model could not only improve the computational efficiency of unsteady fluid flow in the fractured rock,but also avoid the influence of isolated fractures.Finally,the applicability of the numerical model is validated by two engineering examples. |
