摘　　要：十五滩是西南水运出海中线通道(红水河广西段)中的著名滩险,集急、浅、险、弯于一体,整治难度较大。文章利用实测水文观测资料进行水流条件及碍航特性分析,在此基础上,结合工程实际提出该滩的整治原则,并利用物理模型试验的成果进行航道整治工程设计,设计技术标准不只局限于航道等级对航道尺度的要求,还根据降低流速和减缓比降的需要,将滩口或相应部位作加宽、加深处理,以便改善流态,满足航行要求。工程实施后,扩大了航道尺度,解决了“险”、“窄”、“弯”等问题。Due to the rapid flow,shallow bottom,dange rous zone and curve,Shiwutan shoal is a famous dangerous shoal in the central s ea outlet waterway serving southwestern China (Guangxi section of Hongshuihe riv er),which brings great difficulty to regulation. After analyzing the water flow condition and the feature of navigation barrier based on the observed hydrologi c data,the article proposes a regulation proposal. Furthermore,waterway regula tion design has also been done with reference to the result of physic model test . The design is not only limited to improving the waterway dimension as required for navigation grade. The shoal entrance or relevant locations shall also be wi dened and deepened for the purpose of flow reduction and gradient ratio reductio n. By this way,the flow status will be improved to satisfy the navigation deman d. After project implementation,the size of channel has been enlarged to avoid dangerous,narrow and curve problem.
