水布垭水电站坝基岩体地质模型研究

GEOLOGICAL MODEL FOR ROCKMASS OF DAM FOUNDATION AT SHUIBUYA HYDROPOWER STATION

摘要: 围绕水布垭水电站坝基地质模型研究 ,开展了工程地质调查、岩石力学室内外测试和试验和工程应用的研究。在大量野外工作及理论分析的基础上 ,详细研究了水布垭水电站工程地质岩组 ,地质构造规律及坝基岩体地应力和水文地质条件 ,建立了坝基岩体的概化地质结构模型。开展了针对坝基基本地质模型单元的岩体质量评价 ,提出了坝基基本地质模型单元的岩体力学参数

Abstract: Based on the field engineering-geological explortation and rock mechanics test, a study of geological model for dam foundation of Shuibuya Hydropower Station is carried out. The engineering-geological rock group and rockmass structure for Shuibuya dam foundation are studied. The conceptual geological model for the Shuibuya dam foundation is developed. The results of rockmass quality assessment and rockmass mechanical parameter are presented in the paper.
