一、前言由于鄱阳湖堤线长,防洪标准低,迫切需要加高加固以适应江湖洪水位提高的趋势。如何合理地确定设计水位是一个必需解决的问题。本文根据前人经验,从分析历史洪水资料入手,提出将圩堤设计水位的确定划分为湖盆区与五河尾闾平原圩区两部分。湖盆区主要指鄱阳湖周边,受长江洪水控制,以1980年长江中下游防洪座谈会确定的湖口防 I. Preface Due to the long embankment length of Poyang Lake and the low standard of flood control, there is an urgent need to increase and reinforce to meet the trend of increasing the flood level of rivers and lakes. How to reasonably determine the design water level is a problem that must be solved. Based on the experience of our predecessors, this paper starts with analyzing the historical flood data and proposes to divide the design of the levee dike into two parts: the lake basin and the polders in the Wuhewei plain. Lake basin mainly refers to the surrounding Poyang Lake, controlled by the Yangtze River flood to flood prevention in the middle and lower reaches of the Yangtze River in 1980 forum determined Hukou
