摘要

大岗山水电站地震地质环境复杂,大坝抗震设防烈度高。坝址区以花岗岩为主,穿插辉绿岩岩脉,辉绿岩岩脉及其破碎带发育,岩体风化强烈。在地质调查、勘探、试验的基础上,通过对区域构造稳定性、坝基岩体质量分类、岩体稳定性、混凝土人工骨料勘察等关键工程地质问题的深入研究,查明了大岗山水电站的工程地质条件,对关键工程地质问题进行了准确评价。
        The geological environment of Dagangshan Hydropower Station is complex and the dam seismic intensity is high. The rock in dam area is mainly granite interspersed with diabase dikes. The diabase dikes and their broken belt are developed, and the rock mass is strongly weathered. On the basis of geological survey, exploration and testing, the in-depth researches on key project issues of regional structure stability, dam foundation rock mass classification, rock stability and artificial concrete aggregate investigation are conducted. The engineering geological conditions of Dagangshan Hydropower Station are identified and key engineering geological problems are also accurately assessed.
