This standard specifies the technical requirements on such aspects as dam-site engineering geological investigation contents and methods of hydropower and water resources, research on dam-foundation engineering geological characteristics, dam-site engineering geological evaluation and geological construction work.
This standard is applicable to large-scale dam-site engineering geological investigation of hydropower and water resources. Medium hydropower and water resources with complex dam-site geological conditions may be implemented with reference to this standard.
