摘　　要：通过建立一维、二维水动力数学模型,利用1992年实测地形与2008年和2009年复测断面资料,通过对典型年的洪水位、行洪能力、断面流速和流态等的计算分析,对淮河干流蚌埠段整治工程的效果进行了对比分析。结果表明:蚌埠段整治工程实施后,洪水位显著降低,行洪能力明显增加,流态得到了进一步改善,表明该河段退堤、切滩、疏浚等河道整治措施和规模是适宜的。By establishing one-dimensional and two-dimensional hydrodynamic mathematical models and by calculating and analyzing the flood level,flood discharge ability,sectional velocity and flow regime based on the measured topography in 1992 and the re-measured data in 2008 and 2009,the effect of river regulation in the Bengbu reach of Huaihe River is investigated.The results show that the flood level significantly decreases,the flood discharge ability obviously increases,and the flow regime is improved after the implementation of the regulation project.The relevant measures of embankment withdrawal,shoal cutting and dredging and the scale of the regulation project in Bengbu reach are appropriate.
