| 摘 要： | 文中针对在均质等厚、无限分布的承压含水层中，以定流量抽水时，抽水主孔附近含水层会存在非线性流区域的问题，根据水量平衡原理，分别建立了线性流区域和非线性流区域的水流运动方程，采用Boltzmann变换对其求解，得到了计算两个区域中任一点的渗流速度和水位降深的解析公式。

| Abstract: | The analytical solution describing seepage velocities and draw-downs both in linear and nonlinear flow zone have been derived, in case there is a nonlinear flow zone near the pumping well in the investigated aquifer which is extending infinitely with constant thickness. At the same time the pumping rate is assumed to be constant. |

| Keywords: | two flow-regime nonlinear flow well flow analytical solution |
