高速铁路出入口选择及设计原则

PRINCIPLES OF SELECTION AND DESIGN OF INTERSEC-TIONS FOR HIGH SPEED RAILWAYS

高速铁路上行驶的跨线列车要通过高速铁路与相邻铁路的出入口完成转线任务，出入口是高速铁路设计的组成部分。本文根据对京沪高速铁路徐州至上海段的路线列车对数的研究，对无锡、南京、浦口、蚌埠、符离集、徐州等处要否设置出入口和如何设置提出了设想和分析；对出入口的设计范围和设计原则提出了初步意见。

The overpassing trains in the high-speed railways must pass through the pointswhich intersect the nearby railway for changing lines.Designing the intersections are thecomponent parts of the design of the high-speed railway.According to the study result forthe number of overpassing trains in pairs in the Xuzhou-Shanghai Section of the Jing-HuHigh-speed Railway,this paper suggests the ideas and analyses questions whether the inter- sections are set at Wuxi,Nanjing,Pukou,Bengfu,Fuliji Xuzhou,etc,and the questionshow the intersections are set.Preliminary ideas on the design range and the design principleare suggested in this paper.
