| 摘 要： | 龙开口水电站有泄流量大、主河床狭窄等特点,对于这类工程泄洪消能尤为重要.为了解决水工模型第一试验阶段挑流消能不充分、闸墩出口流态紊乱的问题,进行了溢流坝段的水工单体模型试验,对连续坎、差动坎、窄缝坎以及差动坎和舌形坎、窄缝坎和舌形坎、窄缝坎和连续坎的结合运用等多个挑坎体型进行了冲刷试验,从而选择适用于龙开口水电站这类泄流量大、主河床狭窄电站的溢流堰挑流鼻坎形式.

| Abstract: | Longkaikou hydropower station has the main characteristics of the riverbed narrow and discharge large,for this type of project energy dissipation is particularly important.In order to solve the hydraulic model tests in the first phase of the trajectory not fully eliminate,the flow of outlet close to the pier disorder,a spillway section of the single hydraulic model tests in the spillway section was carried out,as well as the washed out test such as run ridge,differential ridge,narrow slot ridge,and the tong... |
