对淮干泄洪能力变化的分析,不仅对防洪调度很重要,而且对干流的治理方案有直接影响。本文试通过对干流控制站的实测水位、流量、大断面图,以及行洪堤顶高程变化等资料的分析,探索现今淮河干流泄洪能力较之五十年代的变化,影响和导致河道泄量减少的主要因素。典型年的选择以1982、1956年两年作为典型进行分析计算。这两年洪水干流各站第一、二次洪峰值基本接 The analysis of the change of flood discharge capacity of Huai River not only plays an important role in flood control and regulation, but also has a direct impact on the management of the mainstream. This paper tries to analyze the actual measured water level, flow rate, large section of the main control station and the change of the height of the flood embankment, and other data to explore the current Huaihe River flood discharge capacity than the changes of the 1950s, the impact and lead to reduced river discharge The main factor. The typical year of choice 1982 and 1956, two years as a typical analysis and calculation. In the past two years, the mainstream of the floodwaters first and second peak basic access
