用有限差分模型反求高升水源各项补排量

Using Finite Difference Model to Reverse Various Complementary Displacement of Gaosheng Water Source

根据含水层的结构变化、富水性特征、地下水等水位线的疏密程度,将计算区按三角形单元进行剖分;在计算区域剖分和时间剖分基础上,按均衡原理,建立不规则网格的有限差分模型;利用计算区的长期观测资料,对模型进行识别和验证,并反求水文地质参数和各项补排量。

According to the structural changes of aquifer,water rich characteristics and density of groundwater level line,the calculation area was divided in line with triangular elements. On the basis of calculation area and time division,a finite difference model of irregular net was established based on the balance principle. The model was identified and confirmed using the long-term observation date in calculation area and to reverse the hydrogeological parameters and various complementary displacements.
