| 摘 要： | 由于受干流的顶托影响,弱支流河口段水流、泥沙运动规律复杂,其整治参数已不能用天然河段的计算方法来确定,而经验方法也往往由于缺乏科学性而导致工程事倍功半.在总结赤水河口淤沙河段航道整治成功经验的基础上,探讨了山区弱支流河口段航道整治参数的确定方法.提出应根据干流顶托水位降落过程,分段采用浅滩由淤积转人冲刷、流速较大、冲刷...

| Abstract: | Due to the jacking influence of main stream,the law of flow characteristics and sediment transportation of the feeble branch river estuary reach is complicated.The calculation method of determination to the regulation parameter is not applicable to the natural river reaches.And for the lack of science,the empirical method usually can not achieve good results.In this paper,based on summarizing the succeed experience of channel regulation in estuary reach of Chishui river,the method of determination to channel regulation parameter of branch river estuary reach in mountainous area was discussed.Some new theories of determination to channel regulation discharge,regulation stage and width were put forward. |
