摘　　要：铁路在大修或兴建时线路纵断面设计都是铁路线路大修或兴建中设计最重要的环节之一,它根据轨面正线的黄海高程反应地面起伏情况,原坡度是否符合规范设计,为了保证坡度能够使用平断面和纵断面要紧密配合设计,逐段在同时满足平面、纵断面设计要求下设计,纵断面的设计直接影响到铁路线路的运营指标和铁路维修标准,纵断面的设计主要有:线路纵面的设计对铁路列车提速、货车吨位、建造工程的标准有着很大的影响,纵断面设计主要接解决的问题是坡度设计,坡段长度比选、竖曲线的设置、还有既有道床的维修和设计线道床厚度的设计。During railway overhaul or construction,the design of line profile is one of the most important links in the design of railway overhaul or construction.It reflects the ground fluctuation according to the Yellow Sea elevation of the main track on the track surface,and whether the original slope meets the standard design.In order to ensure that the slope can be used,the design of plane and profile should be closely coordinated,and the design should meet the design requirements of plane and profile section by section at the same time.The design of profile directly affects the operation index and railway maintenance standard of railway line.The design of profile mainly includes:The design of line profile has a great impact on the speed increase of railway train,the tonnage of freight train and the standard of construction engineering.The main problems to be solved in profile design are slope design,comparison and selection of slope section length,setting of vertical curve,maintenance of existing track bed and design of track bed thickness.
