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。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。Shiwu Shoal is the famous dangerous shoal of the middle-line waterway to sea in Southwest China. The current is swift, shallow, dangerous and curved, so is very difficult to be regulated. Based on the analysis of the current conditions and characteristics of hindering navigation by hydrologic records, the regulation principle and designs are proposed from the results of physical model tests. The technology standard will not only satisfy the requirement of the channel grade,but also make the corresponding section of the shoal wider and deeper according to the requirements of slowing down the current velocity and slope. The channel scale will be enlarged and the above difficulties will be solved after the construction.
