清水工业园某场区地下水动态变化分析及预测

为探究地下水动态变化原因和防治措施,以清水工业园内某化工企业场区为研究对象,对地下水动态进行预测研究。通过对该场区水文地质条件的勘查,在了解地层结构、地下水的分布特征和水力特征、地下水和地表水的补排情况等基础上,分析在降水入渗补给、地下水侧向径流补给和西湾露天矿排水等因素作用下,场区地下水动态影响因素,并对地下水进行了动态预测。结果表明,该场区地下水水位变幅较大,具有双峰特征;当上游地下水侧向补给量完全消失时,场区的地下水位将最大下降近30 m;受西湾露天坑排水及场地硬化影响,场区地下水位将大幅度下降,最大下降近50 m。

Analysis and prediction of groundwater dynamic change in an site of Qingshui Industrial Park

In order to explore the causes of groundwater dynamic change and control measures,taking the site of a chemical enterprise in Qingshui Industrial Park as the research object,the groundwater dynamic was predicted.Based on the investigation of hydrogeological conditions of the site,and the understanding of stratum structure,distribution characteristics of groundwater,recharge and drainage of groundwater and surface water,the dynamic influencing factors of groundwater in the site were analyzed and the dynamic prediction of groundwater was predicted under the influence of precipitation infiltration supplement,groundwater lateral runoff supplement and drainage of Xiwan open pit mine.The results show that the groundwater level in the site area varies greatly and has double peak characteristics.When the lateral recharge of the upstream groundwater disappears completely,the maximum groundwater level in the site area will drop by nearly 30 m.Affected by the drainage of Xiwan open pit and the hardening of the site,the groundwater level in the site area will drop significantly,with a maximum drop of nearly 50 m.
