补充资料：地下水位下降漏斗
地下水位下降漏斗
water-table depression cone
d ix旧shuiwei xiajiang loudou地下水位下降漏斗(water一table depres·sion cone)当地下永开采量大于补给量时，地下含水层产生向下凹陷的自由水面或水压面(前者指潜水含水层的水位，后者指承压含水层的水位)状似漏斗 漏斗的类型有季节性.‘漏斗”和常年性“漏斗”季节性漏斗:主要受气候和开采因素的影响，常出现在干旱季节。降水季节，由于入渗、补给，水位逐渐恢复，漏斗随之消失。常年性漏斗:由于长年超量开采，形成的漏斗，虽经雨季，地下水位(水压)有所回升，但漏斗仍然存在。 漏斗造成的不良后果:①漏斗面积不断扩展，水位持续下降，会造成井中水浅或无水而报废，或必须更换水泵;②由于被开采的总厚度较厚的含水层(组、段)中的水被取出，含水岩层的孔隙失去水压力的支撑，在上覆地层压力下，会造成地面沉降或塌陷;③在浅层淡水与咸水交替分布区，因过量开采，使淡水水压减低，四周咸水体向淡水体挤压，上覆咸水体向下入渗，下垫咸水体向上顶托补给，逐渐使淡水体或淡水层(段)的水矿化度增高，水质变坏;④滨海地区，因超量开采地一F水，淡水层压力水头降低，地下水流向和水力坡度改变，在隔水条件较差的地段，出现海水入浸倒灌，或海水沿构造破碎带入渗补给淡水含水层，造成水质变坏。(陈君联)
