the balance of groundwater

According to the groundwater balance theory,the groundwater isostatic essence under the conditions of natural and current mining for confined aquifer II in the west region of Xishan has been analyzed.从地下水运动均衡原理的角度分析了锡山市西部地区第Ⅱ承压含水层天然和现状开采条件下的地下水均衡要素,揭示了该地区地下水开采与地面沉降的关系,其中现状开采条件下的75%～80%的开采量来自于粘性土层的压密释水量;同时,根据地面沉降的发生机理剖析地面沉降严重发育地区忽略地面沉降影响因子建立的地下水资源计算模型中存在的问题,提出了地下水可开采资源合理的计算方法,并对考虑地面沉降影响因子的地下水资源计算模型的可实现性进行了分析。D4m汉语字典
