假定承压含水层均质等厚,水平方向分布无限大,顶底板完全隔水,地下水天然水力梯度大于零,且补给边界与排泄边界距抽水井无限远,那么,这样的含水层中的地下水,以层流状态向单个完整抽水井流动的地下水流系统,就是我们所要讨论的井流系统。本文从研究等势线及流线着手,建立了瞬停状态的瞬时 Assuming that the confined aquifer is of equal thickness and with infinitely horizontal horizontal distribution, the top and bottom plates are completely water-insulated, the natural hydraulic gradient of groundwater is greater than zero, and the recharge boundary and discharge boundary are infinitely far away from the pumping well, then the groundwater in such aquifers The groundwater flow system, which flows in a laminar flow direction to a single complete pumping well, is the well flow system we are discussing. This paper starts from the study of the isopotential lines and the streamlines, and establishes the instantaneous instantaneous stopping state
