摘　　要：在均质等厚、水平各向同性而竖向异性、无限分布的承压含水层中,以定流量抽水,根据水量平衡原理,建立了二维非线性水流运动方程,并针对确定的非线性渗流规律,用Boltzmann变换对方程进行了求解,推导出了二维非线性井流问题渗流速度和水头降深的解析表达式。In homogeneous, equal thick, the level of isotropic, the vertical different, the confined aquifer unlimited, the pumping constant, the water flow equation of the two-dimensional nonlinear flow in the region has been established under the principle of water balance. According to the nonlinear seepage law, the equation has been solved by Boltzmann transform. The analytical expressions of the seepage velocity and the drawdown of the two-dimensional nonlinear well flow problems have been derived.
