| 摘 要： | 沧州市地面沉降过程中地层压密释水导致水资源组成发生变化,这部分释水量是水均衡计算中必须要考虑的,但现有的调查数据并不明确。通过地下水中氟离子浓度的变化来解释地面沉降与弱透水层释水机理,并采用二元混合模型估算地下水开采资源组成中越流与释水所占份额。结果显示:沧州市承压含水层中氟离子浓度与地面沉降量存在着对应关系,在压缩释水阶段,开采量中有56%来自黏性土压密释水;在越流发生阶段,开采量中有36%来自越流补给。这表明压密黏性土释水是水资源评价的重要组成部分。

| Abstract: | Water released from compaction of the aquitards is an important component for water budget,which must be considered in water balance calculations.However,little is known how land subsidence and processes impact on water release.In this work,mechanisms of released water from land subsidence and aquitard were explained by calculating fluorine mass balance in Cangzhou.Binary mixture model was also used to evaluate proportion of cross flow and water release in process of groundwater exploitation.The results sug... |
