摘　　要：　泄水闸在大淹没出流条件下的泄流能力的计算方法至今尚不完善。笔者在十多座低水头水利枢纽模型试验的经验基础上,再进行大量的断面模型试验研究,提出涵盖面较广的泄流能力的计算方法的雏形,试图对此类工程在建闸后的闸前壅水情况进行较全面地估算。The calculation method for discharge capacity of sluice under highly submerged discharge is still not perfect now. Based on the experience in model tests for more than ten lower-head hydraulic projects and a lot of cross-section model experiments, this paper presents a calculation method for discharge capacity of sluice under highly submerged discharge which provides a more complete estimation of the water level increment in front of the sluice after its construction.
