The reservoir control drainage area is 985km2, occupies Ying river drainage area 7230km2 13.6%, occupies Ying river massif area drainage area 1900km2 51.8%, is by prevents floods and the irrigation primarily, proper attention to both industrial water supply, aquaculture, traveling large and so on comprehensive utilization large -scale key project. Baisha reservoir total storage capacity 278 million m3, Flood prevention Standard stipulated according to GB code, The Baisha reservoir project bank should be is big (2), The floodgate is 2 levels of buildings, the floodgate design standard is 100 years as soon as meets, The examination standard is in 2000 as soon as meets. According to Spillway Design Standard (SL253 -2000) under the floodgate the design standard of Disappearing energy and guarding against flushes meet according to 50 years, The examination standard meet as soon as 100 years. This design is the Baisha reservoir except dangerous reinforcement project in spillway design, including following several aspects content: Plan comparison and choice as well as water power computation, structural stability computation includi
