| 摘 要： | 水电枢纽下泄非恒定流具有日水位、流量频繁大幅波动的特点,对下游河道的河床演变与通航条件产生了严重影响。针对枢纽下泄非恒定流作用下河床演变与航道整治的特点,建立了贴体正交曲线坐标系统下的韩江上游二维水沙数学模型;在运用大量水沙实测资料对模型详细验证的基础上,对推荐方案实施后的整治效果与非恒定流对航深的影响进行了计算。

| Abstract: | The unsteady flow released from hydraulic power stations is characteristic of the great changes of water level and runoff during a day,which brings great effects on riverbed process and navigation conditions of the downstream reach.According to the characteristics of riverbed process and channel regulation affected by unsteady flow,a 2D mathematical model is developed in the upstream reach of the Han River,which adopts the boundary-fitting orthogonal coordinate system.Based on the verification of the water level process and the riverbed deformation,both the regulation effects after the implement of the recommended projects and the navigable guarantee rate affected by unsteady flow are predicated. |
