摘　　要：利用平面水流数学模型，通过水位和流场验证后，对建库后黄草峡河段万吨船队通航条件进行了模拟分析。对突咀和卡口段进行窄深和宽浅两种挖槽型式的整治工程后，计算分析表明，宽浅型挖槽更适用于该类型滩段。同时，对成滩和通航流量进行了分析。Based on plane flow mathematics model and verification of water stageand field of velocity, the sailing condition of ic,im dwt fleet in Huangcaoxia reach afterbuilding of reservoir is modeled. Two kinds of regulation measures, i.e., narrow-deep andwide-shallow excavation for protruding lips are calculated. The results show that wide-shallow excavation is more suitable for gorge reach. In addition, shoal formation andsailing discharge are analyzed.
