摘　　要：在分析长江中下游岸线开发利用现状及存在问题基础上,分别选取武汉河段和扬中河段作为代表性河段,针对桥梁群和码头群两类主要岸线开发利用形式,开展了涉河工程群对河道洪水位及流场累积影响的数学模型计算分析。计算结果表明,群体工程共同作用后将引起河道洪水位和流场的叠加影响,其影响值及影响范围远大于单个工程,当群体工程的影响积累到一定程度,可能对河道的行洪与河势稳定带来不利影响。建议桥梁群应保持合理的密度,码头群应合理控制港区规模,上下游港区间应保持合理的距离,在岸线开发过程中应制定岸线利用规划,规范涉河工程设计,以尽可能减小对防洪的累积影响。Based on the analysis of the present situation and existing problems of the bankline use in the middle and lower reaches of the Yangtze River,with the mathematical model research method,taken bridges in Wuhan river reach and dock groups in Yangzhong river reach as examples,the calculation of accumulated influence on river flood water level and flow field by lots of wading engineering groups were carried out.Results showed that the flood water level and velocity influence were accumulated after the wading engineering groups built and the influence of wading engineering groups was much larger than that of single engineering.When the influence was increased to the extent,it would do harm to the river regime and flood carrying capacity.In the end,some suggestions are given,such as the bridge density and dock group scale should be controlled reasonable,the principle of the bankline use should be put forward,river engineering design should be regulated,and River regulation should be strengthened,in order to minimize the cumulative effects of flood control.
