【摘要】 综合分析了由于地下水过量开采及三废排放等原因引发一系列环境水文地质灾害问题,诸如地下水水位持续下降形成区域地下水降落漏斗并不断扩张、含水层疏干、海水入侵、供水井吊泵、地面沉降和塌陷等,并初步探讨了灾害发生过程中的力学机制,对引发环境水文地质灾害的动力学因素进行详细阐述。研究结果表明:以多孔介质中孔隙水运移规律为主线,结合地下水动力学、岩土力学、水文地质学原理进行多学科交叉综合研究,动态地预测预报在未来环境水文地质条件下地面变形、溶质运移和浓度扩散状况与趋势,并且根据预测预报结果提出相应的工程防控措施,可为水文地质部门灾害的防治提供决策依据,这对于定性研究灾害发生发展的预测预报具有重要的现实意义。更多还原

【Abstract】 The principal environmental hydrogeological disaster problem,which caused by the groundwater depression,groundwater pollution,saltwater intrusion because of the excessive exploitation of groundwater and the discharge of the wastes are comprehensively analyzed.Hence discussed mechanical mechanism of the disaster process.The dynamic factors caused environmental hydrogeological disaster are also reviewed in detail.Results show the focus should be put on the transport law of porous water the intercross of several subjects.The mechanism of the disaster process is analysized by using the groundwater hydraulic,rock and soil mechanical,environmental hydrogeology.It dynamically predict the surface deformation,solute transport and concentration dispersion The author put forward some countermeasures to prevent and reduce these environmental hydrogeological disasters,which are provided the best policy for the local hydrogeological government.It has great practical significance for qualitative analysis the prediction and forecast problem of environmental hydrogeological disaster development.更多还原
