地下水流三维数值模拟中弱透水层初始水位的推求方法分析

Analysis on the Method to the Initial Groundwater Level of Aquitard During Three Dimensional Transient Numerical Simulation of Groundwater Flow

弱透水层初始水位对地下水流三维数值模拟模型的计算结果有较大的影响,并且这种影响在模型运行的初始阶段表现最为明显。取上下相邻含水层水位平均值或以稳定流模拟结果作为弱透水层初始水位的方法可以在一定程度上减小赋值误差。

The initial distribution of taquitard has a certain extent affection for the simulated result of 3-D groundwater transient flow. The affection was showed obviously in the initial phase during simulation process. In order to reduce the error between real groundwater level and supposed groundwater level, the average of adjacent aquifer groundwater flow level or the steady flow simulation results can be evaluated to the aquitard.
