摘　　要：分析了峰下第一制动位减速器安全允许入口速度、难行车的最低过岔速度、加速坡与中间坡间竖曲线与第一分路道岔在平、纵断面布置上的相互制约关系;论证了峰顶至第一分路道岔的合理距离;探讨了加速坡的合理坡度和坡长;指出了《站规》中将加速坡极限值定为65‰的不可能性。This paper gives an analysis of permissive entering speed at the first set of retarders, min. speed on turnouts of hard rolling cars and the interlocking of plane and profile layout between the vertical curve of acceleration grade and intermediate grade and the first shunting turnout. It also proves the proper distance between the hump crest and the first shunting turnout, proposes the appropriate gradient and length of acceleration grade, and points out the impossibility of the limitation 6.5% gradient of acceleration grade specified in Station Rules and Regula-
