市域铁路轨道系统关键技术创新

Key Technological Innovation in Track System of Suburban Railway

我国市域铁路轨道系统关键技术研究刚刚起步,尚不能满足目前市域铁路建设和发展的需求。以温州市域铁路为依托,结合市域铁路的功能需求和技术特点,开展无砟轨道、道岔、减振降噪、无缝线路等关键技术研究,研制扣件、道岔、减振产品等市域铁路轨道核心装备,形成我国具有自主知识产权的市域铁路轨道系统设计技术,研究成果为建立符合我国国情的市域铁路轨道技术标准体系提供了支撑,对促进我国市域铁路发展具有重要意义。

The research on key technologies for track system in China’s suburban railway is still in its early stage and cannot meet the current requirements for the construction and development of suburban railway. Based on the suburban railway in Wenzhou City and considering the functional requirements and technological features of suburban railway, researches are conducted on key technologies including ballastless track, turnout, vibration ＆ noise reduction and seamless line. Thus the team develops core equipment in suburban railway such as fastening, turnout and vibration reduction products, and establishes China’s design technology for suburban railway track system with independent intellectual property rights. The research achievements provide support for the establishment of the technological standard system for suburban railway track which fits China’s situation. They are of important significance to the development of China’s suburban railway.
