摘　　要：本文介绍了某高水头弧形闸门拟采用的三种框形伸缩式水封的切片试验方法及成果。试验表明：三种水封在一定背压下均能封住间隙２０ｍｍ，水头１２０ｍ的漏水。其中Ｉ型水封封水背压最大，Ⅱ型次之，Ⅲ型最小。The paper presents the method and results about experiment on three types of seals with expand and contract which are used to high head radial gates. Results show that three types of seals can be watertight at some rear pressure when clearance is less than 20 mm and water head is not higher than 120 m. The rear watertight pressure for type one is highest, that for type two is second, that for type three is lowest.
