近年来,随着钢铁企业升级改造,以及用地的日益紧张,铁路曲线半径问题在钢铁企业总图运输设计中显得尤为重要。文章论述了钢铁企业铁路改造设计中,频繁面对的准轨铁路最小半径选择的理论依据,同时给出了相应的工程技术措施,以及在设计与生产管理中应侧重注意的问题。 In recent years, with the upgrading of steel enterprises and the growing shortage of land, the issue of railway curve radius becomes more and more important in the design of general layout of steel enterprises. This paper discusses the theoretical basis of the selection of the minimum radius of the quasi-orbit railways frequently encountered in the design of railway reconstruction in the iron and steel enterprises. At the same time, the corresponding engineering measures are given and the problems that should be paid attention to in design and production management are given.
