摘    要:为建立滨海平原深层地下水水源地,以某一水源地勘探为例,采用水文地质测绘、物探、钻探及抽水试验等多种手段勘查,研究滨海平原水文地质特征及水资源开发约束条件。结果表明,在地下300~700 m存在两个矿化度不大于2 g/L的深层地下水开采段,每个开采段涌水量约40 m3/h;深层地下水距补给区较远,地下水迳流缓慢,主要排泄方式为人工开采,受人工开采影响,天然地下水流向已被改变,适宜建立应急水源地;在概化面积52 km2的范围内建立1.7×104 m3/d的水源地,地面沉降、咸水运移及海水入侵问题在10年内不会影响水源地的正常运营。

Abstract:In order to build deep groundwater resource in coastal plain,with a water resource exploration as an example,we adopt multiple approaches such as hydrogeological mapping,geophysical prospecting,hydrogeological drilling and pumping test to study hydrogeological characteristics and constraints.The results show that there are two deep groundwater mining sections in 300-700 m with mineralization degree of no more than 2 g/L,and inflow of water in each mining section is about 40 m3/h.Deep groundwater is far from supply area,and groundwater flow is slow;main groundwater discharge way is artificial exploitation,and natural groundwater flow direction has been changed,emergency well-field can only be built.1.7×104 m3/d well-field can be built in the general area in the range of 52 km2,and in 10 years environmental geological problems will not affect the normal operation of well-field.
Keywords:Coastal plain  Deep groundwater  Exploitation plan  Environmental geological problems
