摘　　要：通过分析大藤峡库区武宣县城区防洪排涝、七星河消落带治理等需求,综合考虑大藤峡水库运行方式,确定城区防洪排涝总体布局。七星河泵站是武宣县城七星河防护体系的一部分,为确定七星河泵站规模,根据大藤峡水利枢纽运行方式和干支流洪水遭遇情况,分析确定其抽排设计工况为主汛期干流20年一遇洪水遭遇支流2年一遇洪水,研究成果可为库区泵闸规模分析提供参考。By analyzing the needs of flood control and drainage in Wuxuan county, Qixing river fluctuation zone, and considering the operation mode of Datengxia reservoir, the overall layout of flood control and drainage is determined.According to the operation mode of Datengxia water project and the analysis of flood encounters of main stream and tributaries, the design condition of pumping and drainage is determined.As a result, the main stream meets the flood every 20 years and the tributaries meet the flood every 2 years in the major flood period, and the scale of Qixinghe pump station is determined.
