摘要
新疆某水电站工程采取冬季施工,通过调查水电站库区工程地质及水文地质条件,分析总结了影响冬季施工的工程地质问题的决定性因素,并从水库渗漏、库岸稳定、水库浸没(淹没)和水库诱发地震等方面进行了评价。评价结果表明,库区工程地质条件较好,满足修建大坝的要求,所选择的碾压式沥青混凝土心墙坝抗震性和防渗性能较好,施工简单,可冬季施工,使工程提前发电,总工期也相应提前,提前发电产生的经济效益十分显著,可为高寒冷地区类似地质工程提供参考。
The hydropower station engineering constructed in winter. Analysis and summary decisive factors of engineering geological issues which influenced construction in winter by investigation on engineering geology and hydrologic geology of reservoir area of hydropower station. The paper evaluated reservoir leakage,stability of reservoir bank,reservoir immersion（ submerged） and reservoir induced earthquake etc. Evaluation results show that reservoir area engineering geological is better and meet the build dams. Rolling type asphalt concrete core wall dam seismic and anti- leakage is better,construction is simple,its can constructed in winter which power generation was advanced,total time of construction was also advanced. Power generation advance produced economic benefits quite obviously. The paper can be as references for similar projects in server cold region.
