结合参与郑西、武广客运专线设计体会,就高速客运专线线路设计执行《京沪高速铁路设计暂行规定》中的若干问题,提出探讨性建议。包括:线路平面设计的最大曲线半径选用、缓和曲线长度及曲线超高设置;线路纵断面设计的最大坡度、最小坡段长度、坡段连接;平、纵断面组合设计等。 Combining with the design experience of Zheng-Xi and Wu-Guang Passenger Dedicated Lines, this paper puts forward some suggestions on how to design and implement “Interim Provisions on Design of Beijing-Shanghai High Speed ​​Railway” for high-speed passenger dedicated lines. Including: the maximum curve radius of the line design, the length of the curve and the setting of the curve; the maximum gradient, the minimum length of the slope, the connection of the slope; the combination of the flat and vertical sections.
