GEOLOGICAL MODEL FOR ROCKMASS OF DAM FOUNDATION AT SHUIBUYA HYDROPOWER STATION

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.
