我国西部地区水电建设中工程地质问题探讨

Study on the Geological Problems of Hydropower Construction Engineering in the Western Regions of China

本文结合目前在建的以及已建的水电站,探讨了水电建设中面临的一系列工程地质问题,包括地震、活断层对区域构造稳定的影响、高边坡稳定问题、深埋长隧洞稳定问题、深厚河床覆盖层、冻土地质灾害、复杂水文地质条件和高地应力岩体卸荷等。

This paper combines with currently under construc-tion and existing hydropower station, discusses a series of eng-ineering geological problems in hydropower construction, incl-uding earthquakes, active faults on the impact of regional tect-onic stability, slope stability, long deep tunnel stability, deep bed cover layer, the permafrost geology disaster, the complex hydrogeological conditions, and high stress rock mass unloadi-ng and so on.
