摘　　要：研究目的:根据新的技术政策、新的标准规范等要求,通过对既有线扩能改造中出现的与新的标准规范不相适应的若干问题的分析研究、对既有线通行双层集装箱的合理性及增建二线后改变维修体制的探讨,提出了觖决既有线扩能改造工程若干问题的基本思路。研究结论:对于既有线扩能改造工程的一些问题,应根据项目的特点,在本着避免既有线大拆大改、节省工程投资的原则下,结合铁路新的技术发展方向、新的标准规范要求,采取具体问题具体分析,对于新建线路应不折不扣地执行新的标准规范,对既有线改建则应充分考虑到既有线的现状特点,在满足项目功能需求的情况下,应尽可能地与新的标准、规范相适应,并应考虑未来的发展需要。Research purposes： According to the requirements of the new technological policy and new standards and codes,and based on the analysis of and study on the problem that the upgrading of existing railway is not adaptive to the new standards and codes,in this paper the discussions are made on the rationality of double-stack container for existing railway and change of the maintenance system after building the second line,and the basic thoughts are presented on solving the problems in upgrading of the existing railway line.Research conclusions：The problems in upgrading of existing railway line should be analyzed concretely on the basis of project character,the development trend of new railway technology,the requirements of new railway standards and codes and the principle of avoiding too much demolition and change of existing railways.The newly built railway line must meet the new standards and codes completely,and the upgrading of existing railways should consider the current situation of the existing railway line and the development situation in future,and is adaptive to the new standards and codes as much as possible under condition of meeting the needs of project functions.
