摘　　要：目前在防洪排涝工程规划设计工作中,黑龙江省内大家最常用,而且问题最多,争议也最大的方法就是组合方法Ⅰ,即设计排水区内的不同类型排水分区,采用不同的方法,单独计算排水流量后,直接相加的流量作为整个排水区的设计排水流量。因此,文章重点对组合方法Ⅰ在基本假定、适用条件、应用范围、参数内含及计算精度等诸方面进行了综合分析,并提出了解决方法。In current planning and design work of flood control and draining waterlogged projects,the most controversial approach used most commonly in Heilongjiang Province is the combination methodⅠ,it is to adopt different methods to calculate the discharge added directly after calculating separately the drainage discharge based on different types of drainage region within the design drainage area as the design drainage discharge of the whole drainage area. Therefore,the focus of this paper is to analyze comprehensively the combination method Ⅰ in respects of basic consumption,suitable conditions,application scope,parameter content and calculation accuracy,and put forward the solution method.
