摘　　要：论述了点连式驼峰溜放部分纵断面的设计方法。驼峰各坡段的设计特点是：用易行车在有利的溜放条件下，从峰顶溜到Ⅰ制动位有效制动长度的始端，其速度不超过容许的最大速度（７ｍ／ｓ为约束条件）来设计加速区，用难行车在不利的溜放条件下，从峰顶溜到Ⅱ制动位有效制动长度的始端，其速度不超过容许的最大速度（７ｍ／ｓ为约束条件）来设计高速区。减速区的坡度应尽可能使易行车在有利的溜放条件下不加速，其坡度可采用０．０‰～２．５‰．打靶区的坡度一般采用０．６‰～１．０‰。A methed for designing the profile on distribution zone of a pointcontinued hump is presented. The gradients on various sections of distribution zone are designed by limiting the rolling speed of wagons running from hump crest to the beginning point of effective braking length at some biaking position under certain condition within the maxinum allowable value of 7 m/s. For accelerating area, the easy running wagons under favorable condition and the braking position I are taken; while for high speed area, the hard running wagons under infavorable condition and the braking position Ⅱ are taken into consideration.The gradient within retarding area may take a value of 0.0～2.5‰ so that the acceleration of easy running wagons under favorable condition probably does not occur, and the gradient within shot area may have a value of 0.6～ 1. 0‰.
