摘要
我国南方圩垸地势平坦,大部分高程均在江、河(湖)洪枯水位之间,因此汛期容易受洪涝灾害影响。在分析南方圩垸地区特点的基础上,提出了除涝的措施,即增加抽排能力、增加水域滞蓄能力和两者结合的3种方案。再采用等效年值法,对3种方案进行投资比较,最终选择等效年值最小者为最佳除涝方案。例证表明,该方法合理可行。
This paper present a method to determine the mode of wipe off waterlogging on dyke area on analysis of water characteristic. This have three methods, as increasing water pump, increasing water area and combining. Then we compared investment by equivalent- yearcost , and choose the best method. The production showed that method is feasible.
