摘要
利用自动水位监测系统获取精确水位数据,分析研究抽水试验和回灌试验渗流变化特性及规律。结果表明:抽水试验异层水位变化时间存在差异性,承压水层水位变化有明显滞后性;回灌试验同层水位变化同步。这为同类条件下基坑工程的回灌方案优化设计提供了参考依据。
The characteristic and law of seepage change of pumping test and recharge test are studied based on the accurate water level data read from the automatic water level monitoring system.The study results show that the water level of different layer changes at different time in the pumping test(the variation of water level of the confined aquifer water has an obvious time lag) while in the recharge test the water level of same layer varies at the same time.It gives a reference basis for the optimization of recharge scheme for the excavation engineering at the similar conditions.
