摘　　要：哈齐铁路客运专线位于严寒地区,采用CRTSⅠ型板式无砟轨道。为尽量减少线间排水引起的对路基和轨道结构的影响,对路基地段线间排水方案进行研究,提出线间设置集水井、底座内设置横向排水管和底座间设置横向排水通道3个方案。结合本线特殊的气候特点,推荐采用底座间设置横向排水通道方案,并对该方案排水设计进行简要说明。Haerbin-Qiqihaer Passenger-dedicated Line is located in the severe cold area, on which CRTS- I slab ballastless track is used. In order to minimize the influence on the subgrade and the track structure because of the drainage between tracks, the scheme of drainage between tracks in subgrade section is researched, and three schemes including the catchpit installed between tracks, horizontal drain-pipe installed in the base, and the horizontal drainage channel installed between the bases are proposed in this article. And then according to the special climatic characteristics of the line, the scheme of horizontal drainage channel installed between the bases is recommended, and a brief description of the drainage design according to this scheme is given.
