小浪底水利枢纽库坝区主要环境工程地质问题分析

Analysis of Main Environmental Engineering Geological Problems in Dam Region of Xiaolangdi Reservoir

根据现场资料 ,对小浪底水利枢纽库坝区主要环境工程地质问题发育的地质环境、形成机理、变形破坏特征、可能造成的灾害程度等进行分析 .结果表明 ,随着库水位的逐渐升高 ,水库蓄水引起的近坝库岸稳定、库坝区渗漏、水库诱发地震及水库淤积等环境工程地质问题已开始孕育和发展 ,有的问题已经出现 .

Based on the field data, some factors related to environmental engineering geological problems at the Xiaolangdi Reservoir are analyzed, including the geological environment in the dam region, the formation mechanism of the geological environment, the characteristics of deformation failure, and the failure induced calamity. The results show that, with the rise of water level in the reservoir, some problems occur, such as seepage in the dam region due to water storage, reservoir induced earthquakes, sediment deposition at the bottom of the reservoir, etc. and some of the problems have already occurred.
