铁路纵断面设计是影响铁路初期建设投资及长期运营条件的基本因素之一,迄今仍乏足够的理论研究。根据全国铁道科学12年远景规划第八项任务中心问题第801“铁路设计主要问题”的要求本文初步讨论铁路纵断面相邻坡道设计理论的实质,应用及列车纵向应力传播速度C、衰减系数α与列车速度V对纵向力传播速度C之比值C/V在我国铁路的确定问题。
The design of railway longitudinal section is one of the basic factors that affect the initial investment and long-term operating conditions of the railway. So far, there is not enough theoretical research. According to the National Railway Science 12 years long-term planning eighth task center issue 801 “main problems of railway design” requirements of this paper preliminary discussion of the longitudinal profile of the adjacent ramps design theory, application and longitudinal stress propagation speed C, attenuation coefficient α and train speed V on the longitudinal force propagation velocity C ratio C / V in China’s railway to determine the problem.
