| 摘 要： | 岩溶裂隙介质可视为双重孔隙度介质。根据水流连续性原理、质量守衡和达西定律，建立了裂隙-岩溶承压含水层非稳定流双重介质数学模型，采用有限体积法对其求解，并以深圳龙岗区为例对模型进行验证。结果表明，计算模型与实际水文地质条件比较接近，计算水位与实测水位相吻合。

| Abstract: | The karst fissure medium can be regarded as dual medium of porosity.According to continuity principle of flow,law of conservation of mass and Darcy's law,the dual medium mathematical model of unsteady flow in fissure-karst artesian aquifer is established,and the finite volume method is adopted to get the solution,taking Longgang district in Shenzhen as an example to verify this model.The consistency of the calculated groundwater level and the measured shows this simulation model can well reflect the actual hydrogeological condition. |
