利用液压提升系统在水电站进行导流底孔下闸，在国内尚属首次。通过向家坝水电站工程下闸所取得的一些检测数据，计算出闸门与门槽轨道间摩擦系数的取值范围，根据操作水头，计算出提升闸门所需载荷，就可以正确选取液压提升设备。

It is rare to close the diversion tunnels in hydropower stations with hydraulic lifting system .The practice in Xiangjiaba hydropower station is the first application in China .With the actual measurement data obtained from the clo-sure procedure , friction coefficients between the gates and the tracks in gate slots are calculated .Working load of the hy-draulic lifting system can be estimated under its working head .Then, the devices in the hydraulic lifting system can be selected based on the working load .
