城市轨道交通预制板轨道弹性部件的研制及应用

在轨道交通领域，传统的浮置板轨道系统均存在施工程序繁杂、更换困难等问题。针对以上问题，以预制板橡胶包套为研究对象，从预制道床板系统配套设计、减振橡胶包套生产制造这两个方面进行合理组合和优化设计，开发出一种新的减振垫预制板系统，同步形成产品设计优化、制造工艺条件以及验收标准等成套技术。通过系统的材料、工艺、装配设计、室内试验和优化改进，并通过实际工程示范应用，施工综合进度提高50%以上，减振效果大于10.0 dB。

Development and Application of Elastic Components for Prefabricated Slab Tracks in Urban Rail Transit

In the field of rail transit, traditional floating slab track systems encounter many problems, such as complicated construction procedures and replacement difficulties. To solve these problems, in this study, prefabricated rubber covers were taken as the research objects, and a reasonable combination and design optimization was performed from the aspects of matching the design of prefabricated track slab systems and manufacturing and production of vibration reduction rubber covers. A new type of vibration reduction pad system was developed, and a complete series of technologies was simultaneously formed including design optimization, manufacturing procedures, and acceptance standards. Material selection, construction optimization, design matching, and laboratory tests were conducted, further improved, and finally applied in practical engineering. The comprehensive construction progress increased by more than 50%, and the vibration reduction effect was greater than 10.0 dB.
