摘要

工程水文地质问题是工程活动与地质环境相互作用的结果，其中岩土体和地下水是尤为重要的组成部分。然而，由于其复杂性和缺乏全面系统的研究方法，目前对其的研究相对分散和简单。从机理的地质分析到基于地质规律的地质模型，预测了地质演化的趋势，并提出了相应的解决措施。本文结合中国西部水电工程独特的施工特点，对引起工程水文地质问题的岩土体高架水敏结构及水电工程中存在的问题进行了探讨。工程水文地质问题是根据特殊的水文地质条件，利用水敏感因素(或结构)引入并确定的水库诱发地震、喀斯特库底渗漏、库岸高边坡稳定、坝基、坝肩滑动、关键位置承压水等。

Study on engineering-hydrogeological problems of hydroelectric project

: Engineering-hydrogeological problems arise from the interaction between engineering activities and geological environment, in which rock-soil mass and groundwater are especially important constituents. However, up-to-date 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, the paper predicts the tendency of geological evolvement and puts forward proper measures to solve problems. In this paper, elevated water-sensitive structure in rock-soil mass, which mainly causes engineering hydrogeological problems, and problems in hydropower is discussed based on unique construction in Chinese Western hydropower projects. Engineering hydrogeological problems are reservoir induced 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 by using water-sensitive factors (or structure) according to special hydrogeological conditions.
