中国铁道学会高速系列会议,高速铁路线路设计及行车组织研讨会于1993年4月26～29日在西安召开。与会代表参照国外高速铁路经验、京沪高速可行性研究成果,认为确定我国高速铁路平纵断面标准及轨道路基结构时以下几方面应引起足够的重视:(1)高速铁路线路最大坡度一般选用12‰～15‰为宜,特殊条件下可采用较大坡度(如35‰),但对坡道长度应
China Railway Society high-speed series of conferences, high-speed railway line design and driving organization seminar on April 26, 1993 to 29 held in Xi’an. Participants with reference to the experience of foreign high-speed railway, the feasibility study of Beijing-Shanghai high-speed, that the determination of China’s high-speed railway plain longitudinal section profile and track subgrade structure should be paid enough attention to the following aspects: (1) The maximum gradient of high-speed railway lines are generally selected 12 ‰ ~ 15 ‰ is appropriate, under special conditions can use a larger slope (such as 35 ‰), but the length of the ramp should be
