| 摘 要： | 雨水回灌后对岩溶水的影响分析和效果需要对回灌井和下游的观测井监测数据说明。由于岩溶含水层中岩溶发育极不均匀,在测定地下水位并判定出地下水流向的基础上,连通示踪试验是选择与回灌井相对应的观测井的有效办法。用氯化钠作为示踪剂,监测不同测井不同埋深地下水电导率随时间变化的方法确定了岩溶水观测井选址、岩溶含水层的结构及水文地质条件。示踪试验结果表明,3#观测井(西院井)可用来监测雨水回灌效果,并计算出该地区的地下水势流速在9 m/h～20 m/h之间。该成果对北方地区岩溶含水层回灌和环境评价具有重要的参考价值。

| Abstract: | We need use the monitoring data of the recharged wells and downstream observation wells to explain the impact analysis and effect about rain water after injection to the Karst water.Because of the karst development in the karst aquifer is extremely uneven,the tracer test is the effective means to select observation wells corresponding with the recharged wells on the basis of determining underground water level and the groundwater flow.With sodium chloride as tracer,monitor conductivity changes with time about different buried depth of groundwater of different logging to determine the observation wells location,the structure of the karst aquifer and the hydrogeology conditions.Tracer test results showed that the 3 # observation well(west institute) can be used to monitor the effect of recharging karst fracture aquifer with rainwater on the roof,and calculating the underground water apparent velocity in the 9 m/hour-20 m/hour.This result has important reference value to guide karst aquifer recharge and environmental assessment in northern Chian. |
