城铁高架桥上梯形轨枕减振道床施工技术研究

Study on the Construction Technology of Ladder Sleeper Vibration Reduction Ballastless Bed on the Urban Rail Viaduct

结合国内首次在北京地铁5号线高架桥上成功铺设梯形轨枕减振道床试验段,介绍梯形轨枕减振道床的结构、性能、减振原理,及施工过程中关键施工技术和质量控制要点,对大规模推广使用该道床提出改进建议。

Combining the successful laying of the ladder sleeper vibration reduction ballastless bed test section which is used on the viaduct of Beijing subway line 5 for the first time in China,the author introduce the structure,performance,vibration reduction principle,the key construction technologies and quality control points in the construction process,and put forward the improvement proposal on the large-scale promotion and use of this kind of track bed.
