| 摘 要： | 在系统分析研究区地质及水文地质条件的基础上,运用地下水模型FEFLOW建立了研究区垂向二维非均质流体的对流-弥散数学模型,并通过水位和水质的动态观测资料对模型进行了识别和校正.运用识别后的模型模拟了有填海和无填海两种工况下的海水入侵过程.结果表明:地下水开采是海水入侵的主要原因;在开采地下水条件下,研究区有无填海工程对海水入侵的影响不大,研究区填海工程对海水入侵有一定的阻挡作用,但作用不是很显著.

| Abstract: | Based on the analysis of the geological and hydro-geological condition in the study area,a two-dimensional non-uniform convection-dispersion model was developed to study the salt water intrusion with ground water model FEFLOW.The parameters of model are estimated by comparing with long-term observation data of hydraulic head and chloride concentration.The salt water intrusion process was simulated using the identified model for the cases with and without reclamation.The results indicate that the main reason... |
