| 摘 要： | 根据含水层数学模型的降深-时间双对数和半对数曲线特征,可以确定含水层类型;依据选定的含水层模型,调整其中水文地质参数以拟合抽水试验中观测井降深-时间实测数据,可以反演水文地质参数。将以上方法应用于天津地区6组工程抽水试验,获得试验含水层类型及其水文地质参数。该方法可用于其他相关工程,天津地区和工程建设有关的50m埋深范围内含水层属性及其水文地质参数取值范围,可参考借鉴本文计算结果。

| Abstract: | The log-log and semi-log plots of the theoretical time-drawdown relationships for confined, unconfined,and leaky aquifers possess different characteristics,which can be used to identify the type of aquifer.By adjusting hydrogeological parameters,the calculated values of time-drawdown can best-fit with observed data from pumping tests,then the nearest hydrogeological parameters of pumping field can be obtained.This method was applied to six pumping tests in Tianjin area,which resulted in determination of the types of aquifers and the value range of their hydrogeological parameters.For the similar pumping tests and engineering,especially in Tianjin area,the method and values specified in this paper can be used for reference. |
