摘要 分析了 1 998年长江中下游大洪水特点、崩岸与治理情况 ,从中肯定了崩岸治理的成效 ,提出了存在的问题。提出了崩岸治理分阶段的区分标准 ,对照长江中下游崩岸治理过程 ,大体经历了 60年代以前的自然演变阶段 ,60年代以来的初步治理阶段 ,进展是不一致的 ,其中I级堤防已步入加固改造阶段 ,个别堤段已开始转入岁修维护阶段。认为崩岸治理是控制与稳定有利河势的基本措施 ,是经济可持续发展的基础 ,据此 ,探讨了治崩的 3大策略与举措 。 This paper analyses the characteristics of 1998 flood of middle and lower Yangtze and the condition of bank collapse and its harnessing,confirms the harnessing effect,points out the existing problems and puts forward the stage division standard for the harnessing work of collapsed bank.In the light of the harnessing process of the bank collapse in middle and lower Yangtze,it has generally undergone 2 stages:natural evolution stage before 1960s and preliminary harnessing stage after 1960s.The progress of bank collapse harnessing in middle-lower Yangtze is not the same,for the first grade dyke it has been in reinforcement and reformation stage,and for individual cases it has turned into regular maintenance stage.Bank collapse harnessing is a fundmental measure for controlling and stabilizing favorable river regime and the basis for sustainable economic development.For this reason,this paper discusses 3 main tactics of bank collapse harnessing and some specific measures which may be used for reference in decision making.
