摘要
本文通过对考虑流速垂直分量和弹性释水的Neuman潜水完整井流模型解析解的数值分析,给出了模型的数值计算过程,并结合加速遗传算法(AGA)获取了潜水含水层系统参数,通过应用实例表明,可以取得很好的参数估算效果,并且对比传统配线法可知:所得结果与配线法结果近似一致;利用参数计算的降深与实测降深的拟合优于配线法;不必分抽水初期、末期分别拟合,避免了配线法初期和末期导水系数不一致的问题;实现了利用Neuman潜水流模型获得参数的自动优选,简化了参数估计过程。
Based on the numerical analysis, the analytical solution of the Neuman model that considers the effects of elastic storage and anisotropy of aquifers on drawdown behavior, the calculation procedures of numerical solving Neuman model is presented in the paper. By actually applying in optimized technique of Accelerating Genetic Algorithm （AGA）, the results show that the obtained parameters are verified to have good accuracy and this method can auto-optimize the unconfined aquifer parameters.
