摘　　要：闽江竹岐至侯官河段属山溪性感潮河段 ,水文条件变化快变幅大 ,河床边界复杂 ,整治建筑物多。通过选择有关参数 ,处理工程边界以及进口边界条件 ,用二维河道全沙数学模型计算所得的河床变形趋势与实测情况基本一致。在此基础上 。The Zhuqi Houguan reach of Mingjiang River is a mountain torrent and tidal stretch whose hydrological conditions change fast and greatly. The is river bed boundary complicated and a great deal of regulation works needs to be done. The trend of river bed deformation calculated by a plane 2-D numerical model of total sediment transport is in good agreement with the real conditions. On this basis, scouring and silting of the river bed in Zhuqi Houguan reach caused by regulation works are calculated, and regulation results are analyzed.
