Summary This standard applies to: 1) mainly used in the design intensity of 6, 7, 8, 9 -degree 1, 2, 3 grade roller compacted dam, concrete gravity dam, concrete dam, sluice plains, spillway, underground structure, the intake tower, hydropower penstock and ground plant seismic design of hydraulic structures such as. 2) design intensity is 6 degrees, may conduct seismic calculation, but a hydraulic structures still according to this specification to take appropriate measures against earthquake. 3) design intensity than 9 degrees hydraulic structures or buildings taller than 250m backwater, its seismic safety specialist research and feasibility studies should be conducted after the competent departments for examination and approval. According to the specification of seismic design of hydraulic structures can be designed to withstand seismic intensity, any partial damage, the general handling even after normal operation. Hydraulic structures engineering site or bedrock peak acceleration of seismic intensity scale of the works and should be based on regional seismic geological conditions determined by the following provisions: a) Under normal circumstances, should the use of " Chinese seismic intensity zoning map (1990) " to determine the basic intensity. 2) basic intensity is 6 degrees or 6 degrees above the area or height of over 200m capacity greater than 10 billion m ^ 3 large-scale projects, as well as basic seismic intensity of 7 degrees and 7 degrees above the region of large dams over 150m (1) Type project, its fortification should be based according to specific seismic hazard analysis provides bedrock peak acceleration results assessed. Hydraulic structures should be based on their importance and engineering sites in accordance with Table to determine its basic intensity earthquake-proof projects category. Seismic Design of various types of hydraulic structures design or design intensity earthquake acceleration
