摘　　要：为研究武汉市龙王庙险段综合整治方案实施前后汉江河口段河势、流态、流速、水位及河床冲淤变化等情况,设计了动床模型试验,并进行了模型验证试验.综合整治工程3个方案的模型试验表明,各方案实施后龙王庙段的河势都有不同程度的改善,流速分布趋于均匀,主流线右移,局部冲刷坑缩小,河床冲刷强度减弱.根据试验结果,提出了优化工程方案并得到采纳实施,工程效果良好.A movable-bed model test was designed and verified to study the variations of river regime, flow pattern, flow velocity, water level, and riverbed scour and silting of the Hanjiang River estuary section induced by the implementation of comprehensive regulation of the Longwangmiao section of Wuhan City. Model tests show that the comprehensive regulation according to 3 schemes improves the river regime in different degrees, makes the distribution of flow velocity more uniform, results in rightward shift of main flow stream, dwindles local scours, and decreases the scour strength. Based on the test result, an optimal scheme was put forward and put into application, and good effect was achieved in the project.
