摘　　要：圩区路基和桥梁工程标高的确定需以水文分析结果为依据,文章通过实测资料统计法和等值线分析法综合比较,并按考虑或不考虑排涝站抽排2种情况分别计算内涝水位,结合区域洪水特性和设防工程参照分析得到外洪水位。由于相同重现期、相同时段,泵站开机对圩内水位降低作用明显,因此最终选用了最不利工况下的最高涝水位作为公路内涝水位。The elevation of roadbed and bridge projects in polder areas should be determined based on the hydrological analysis results.This paper comprehensively compares the measured data by statistical method and isocontour analysis method,and calculates the flood level with or without consideration of drainage station pumping and drainage,and analyzes the external flood level with reference to regional flood characteristics and forcing-prevention projects.Due to the same recurrence interval and time period,the operation of the pump station has a significant effect on reducing the water level in the embankment,the highest waterlogging water level under the most unfavorable working conditions was selected.
