铁路线路的技术标准,包括轨距、限界、平面、纵断面、路基、轨道等各部分,本文述及的主要技术标准,是平面和纵断面部分,以曲线半径及坡度为重点,兼及站线长度等。在我国铁路建设工作中,有关线路主要技术标准问题,引起一些评论,并正在从技术政策入手进行研究。对比,国外经验值得研究参考,但各国情况有别,各类线路的运营要求、自然条件和建路背景不同,时间有早有迟,标准多种多样,需加具体分析,才有可比基础。
The technical standards of railway lines, including gauge, limit, plane, longitudinal section, subgrade, track and other parts. The main technical standards mentioned in this paper are the plane and vertical section, focusing on curve radius and gradient, Line length and so on. In the work of railway construction in our country, some major comments on the major technical standards of the lines have been made and some researches are proceeding from technical policies. In contrast, overseas experience deserves research and reference. However, the situation in each country is different. The operational requirements of various types of lines, the natural conditions and the background of the road construction are different from time to time. The standards are diverse and need to be analyzed specifically to provide a comparable basis.
