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。
Using automatic water level monitoring system to obtain accurate water level data, analyzing the characteristics and regularities of seepage change in pumping test and recharging test. The results show that there are differences in the variation time of the water level in the pumping test, and the variation of the water level in the confined aquifer is obviously lagging; This provides a reference for the optimal design of the recharge scheme of foundation pit under similar conditions.
