摘要:

抽水试验是获取水文地质参数的重要方法,为准确获取辽河三角洲滨海湿地潜水含水层的渗透系数,进行了一个抽水孔、两个观测孔的抽水试验。根据单孔抽水试验和多孔抽水试验观测数据,采用潜水非完整井求参公式、巴布什金公式及积分变换等方法计算含水层渗透系数。结果表明,用不同方法计算得出的含水层渗透系数值相差不大。通过试验测定PJ01井组潜水含水层渗透系数为1.15 m/d,PJ03井组潜水含水层渗透系数为0.74 m/d。

Abstract:

Pumping test is an important way of obtaining the hydrogeological parameter. In order to exactly get the permeability coefficient of unconfined aquifer in coastal wetlands in Liaohe River Delta, we gave an extractive test on-site with one pumping well and two observation wells. According to the single hole pumping test and the porous pumping test data, we used the calculation formula non-complete well of dive, the Babushkin formula and the integral transform method to solve the permeability coefficient. The results showed that the value of the permeability coefficient getting by different method had little difference. By analyzing the experimental data,we determined the permeability coefficient of unconfined aquifer of PJ01 well group was 1.15 m/d,and the PJ03 well group was 0.74 m/d.

Key words: Liaohe Delta, coastal wetlands, pumping test, the permeability coefficintent
