| 摘 要： | 承压含水层阶梯流量井流公式与水位恢复井流公式可解决不同流量变动条件下含水层参数求解。针对野外压水试验中流量与水压难以控制且观测精度低, 但阶梯流量压水后水位恢复曲线易于准确观测的特点, 根据叠加原理, 从非稳定承压含水层阶梯流量井流基本公式中推导出阶梯流量水位恢复公式。根据现场阶梯流量压水试验资料进行了含水层参数计算, 验证了公式的可行性。

| Abstract: | The head recovery expression of a fully penetrated well in a confined aquifer and the step-head expres-sion of well flow in a confined aquifer can solve aquifer parameters on different discharge alteration.Both of water flow rate and pressure of water injection test on site are difficult to control and the accuracy is lower than that of head recovery curve.A head recovery expression of confined aquifer with step-pressure was deduced from step-head expression of well flow under principle of potential superposition.Based on field step-pressure injection test data the aquifer parameters are calculated and the feasibility of the expression is proved. |
