大海波水库溢洪道泄流能力试验研究

Studies on the Maximum Discharge of Spillway at Dahaibo Reservoir

溢洪道控制段是控制水流下泄的关键部位。因此,溢洪道控制堰的体型设计,要求尽量增大其流量系数,以提高溢洪道的泄流能力,保证枢纽工程安全。通过水工模型试验研究,对溢洪道控制堰体型作出修改,从而改善大海波水库的泄洪能力。

The control section of spillway is the key section to curb the water flow. The design of the practical weir requires to increase the discharge coefficient in order to improve the maximum discharge of spillway and guarantee the safety of a key control project. Through the test studies of hydraulic model, the design of practical weir is modified and the maximum discharge of spillway at Dahaibo Reservoir is improved.
