摘要：既有线改造是我国城市轨道交通未来实现高质量、可持续发展的重要的长期任务，而技术标准是城市轨道交通既有线改造工程立项、设计与实施的重要依据。梳理城市轨道交通技术标准体系现状，分析现行标准对城市轨道交通既有线改造项目工作流程各环节的适应性。针对当前城市轨道交通标准体系下现行标准对既有线改造存在覆盖面不全、适用性不足、针对性不强的问题，提出城市轨道交通既有线改造技术标准体系构建的两种思路与方案，以及标准体系建设与标准制定的原则。围绕改造判定要求、改造设计要求、改造施工要求、验收与运营前安全评估要求、后评价要求等方面对城市轨道交通既有线改造技术标准编制的重点进行探讨。

Abstract: Renovating existing lines is a key long-term task for achieving high-quality and sustainable development of urban rail transit in China. Technical standards are essential for initiating, designing, and implementing renovation projects. This paper reviews the current technical standard system for urban rail transit and examines the suitability of existing standards for each stage of the renovation process. To address the issues of incomplete coverage, low applicability, and poor relevance of

existing standards, we propose two approaches and schemes for developing a new technical standard system for renovating urban rail transit lines, along with the principles for constructing and formulating the standards. We focus on the technical standards for renovation, including the requirements for renovation determination, design, construction, acceptance, safety assessment, and post-evaluation.

Keywords: urban rail transit; renovation of lines; technical standards; system framework
