摘要 以潜水完整井流理论为基础,依据求解潜水含水层参数的Theis模型近似式,研究了基于抽水试验的粒子群算法确定孔隙潜水含水层导水系数T、渗透系数K、给水度μ等参数的方法和途径。计算结果表明,粒子群算法不仅可行,而且求解精度高,收敛速度比其他方法快,是一种值得在实际中推广应用的求解含水层参数的方法。 Based on the pumping theory of the fully penetrating well, the phreatic aquifer parameters such as the conductivity T, penetrability K and mining yields μ are efficiently determined according to Theis model by using the particle swarm optimization. The calculating results show that the method is with high accuracy and the convergence speed is much higher than any other methods. The particle swarm optimization is worth to be applied to the identification of the aquifer parameters.
