摘要
The authors discussed the steady movement from ground water to fully penetrating well in a confined aquifer, and compared the calculation method of drawdown around fully penetrating well in the conditions of Darcy flow and non-Darcy flow. Using Darcy’s law, Forchheimer equation and the exponential formula of wells to solve the distribution around the head, and compared with the results. It was proved that the linear seepage regularity could not be simply replaced by the non-linear seepage regularity, and the difference and connection between different non-linear flow equations.
