可可托海水电站崩塌灾害发育特征及形成机制分析
|
摘要
在对可可托海水电站地形地貌、气象水文、地层岩性、地质构造、水文地质条件以及工程地质条件等分析的基础上,对该研究区崩塌灾害的分布特征、发育特征以及形成机制进行了分析。研究结果表明:研究区崩塌灾害主要分布于额尔齐斯河左岸的山体陡倾边坡,共分布有27个典型危岩体;崩塌类型岩质崩塌(隐患)为滑移式及倾倒式,崩塌规模均为中-小型;影响因素主要包括地形地貌、地层岩性、地质构造、风化、降水和融雪、地震及人类工程活动等。
The present paper has a discussion on development, distribution and genetic mechanism of avalanche hazard at the Koktokay Hydropower Station based on landform, meteorology, lithology, geological structure, hydrogeological and engineering geological conditions. 27 unstable rock masses and various avalanche hazards are distributed over the left bank of the Ertix River. The influence factors include landform,lithology, geological structure, weathering, rainfall, ice melt water, earthquake and human engineering activities.
