摘　　要：大型工程施工期间常涉及多个导流泄水建筑物联合泄流问题,为准确、快速计算东庄水库导流隧洞泄流能力,便于多方案比较和优化,基于施工水力学理论,提出隧洞淹没出流联合泄流水力计算模型,对东庄水库导流隧洞进行了各种出口流态条件下无压流、半有压流、有压流的全流态水力计算。泄流能力计算结果与试验值基本一致,模型同样适用于隧洞与缺口、隧洞与过水围堰等建筑物联合泄流计算问题。During the large-scale construction,it often involves multiple diversion sluice structures combined discharge issue, for fast and ac-curate calculation of Dongzhuang Reseryoir diversion tunnel discharge capacity for multi-scheme comparison and optimization, this paper presented a hydraulic calculation model for the tunnel submerged flow,combined discharge based on the theory of construction hydraulics, conducted Dongzhuang Reseryoir diversion tunnel full flow- hydraulic calculation under all kinds of tunnel outlet flow pattern conditions of free flow,half pressure flow and pressure flow,the discharge capacity calculation results were consistent with the experimental values,the model was also applicable to the combined discharge flow- hydraulic calculation of the tunnel and tunnel gap,the tunnel and the overflow- cofferdam.
