| 摘 要： | 利用自动水位计记录的抽水试验过程中不同层位含水组之间的动态水位,分析了在抽水试验最初阶段时抽水含水组与非抽水含水组之间的水力联系。研究结果表明:(1)抽水含水层对非抽水含水层存在水位影响效应,在抽水初期,水位影响效应较大;当抽水含水层水位达到稳定或缓慢下降时,水位影响效应随之消失。(2)单位降深水位影响效应显示,上部含水层距离抽水含水层越远,水位影响效应越大;下部含水层距离抽水含水层越远,水位影响效应越小。(3)利用三维地下水流数值模拟方法和应力应变对含水层水位动态影响的原理对水位影响效应机理进行分析,发现水位影响效应与含水层的固体骨架压缩系数(α)、水体积压缩系数(β)、孔隙度(n)和边界控制系数(Cm)等参数有关。 |

| Abstract: | Based on the water level data of different deep aquifers recorded by automatic water gauge in the pumping test,the hydraulic connection between pumping aquifer and nonpumping aquifer in the early pumping stage was analyzed in this paper.The results show that(1) the water levels in nonpumping aquifers were affected as the target aquifer was pumping,and in the early pumping stage,the effect was large,then the effect disappeared as the water level in the target pumping aquifer was stable or slowly down;(2)the further the distance between the target pumping aquifer and the nonpumping aquifer,the less effect to the water levels in nonpumping aquifers;(3)the water level effect in multi-aquifer test was related to the parameters α,β,n and Cm according to the numerical simulation of groundwater flow and the stress change principle. |
| Keywords: | pumping test groundwater flow numerical simulation stress change principle water level effect |
