| 摘 要： | 从地下水运动均衡原理的角度分析锡山市西部地区第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式中存在的问题；针对存在问题，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。

| Abstract: | Based on the equilibrium theory of groundwater movement, the groundwater equilibrium elements are analysed under the natural and present mining conditions for the second confined acquifer in the western areas of Xishan City, and 75%-80% of the mining volume under the present conditions is from the compacting release of the clayey layer; Meanwhile, based on the occurring mechanism for the land subsidence, the problems existed in the computing model of groundwater resources are also analysed because of the neglect of the influence factors for land subsidence in the severely developed areas. Some computing methods are raised therefore for mining the groundwater resources rationally and the realizablity for the computing model of groundwater resources considering land subsidence influence factors are also analysed. |
