摘要
工程水文地质问题产生于人类工程活动与地质环境中岩土体和地下水之间的相互制约和相互作用过程中 ,由于问题本身的复杂性 ,目前对这类问题的研究尚处于相对分散的单一研究状态 ,缺乏系统的从地质机制分析到地质模型抽象 ,进而由模拟再现到发展趋势预测以及治理措施论证的全过程研究。本文在系统分析、总结水电工程中水 -岩和水 -工程建筑的作用类型及特征基础上 ,认为可能出现的工程水文地质问题主要是 :水库诱发地震、岩溶渗漏、库岸及高边坡的稳定、坝基、坝肩抗滑稳定、枢纽区深层承压水问题等。
Engineering-hydrogeological problems are arisen from the interaction between engineering activities and geological environment, in which rock and soil mass and groundwater are the especially important constituents. Howerer, today research on them is relatively dispersive and simple due to their complexity and lack of comprehensive and systematic study methods starting from geological analysis of mechanism to geological model based on geological regularities, then to prediction of the tendency of geological evolvement and taking proper measures for solving the problems. In this paper, according to existence of water-sensitive structure in hydroelectric power project region and based on the comprehensive study of types and characteristics of the interaction between groundwater and rock and soil mass, and groundwater and engineering construction, the possible engineering Hydrogeological problems are reservoir in duced earthquakes leakage from reservoir bottom in karst, stability of high slope at reservoir banks, sliding of dam foundation and dam abutment, and confined water at key positions which are introduced and determined byusing water-sensitive factors (or structure) and according to special hydrogeological conditions .
