无砟轨道是当今世界先进的轨道技术,它克服了高速列车运营时造成的道砟严重粉化、线路维修频繁的缺陷,提高了安全性和舒适性,而且列车时速可以达到200km以上。无砟轨道基础工程的施工是列车高速运行的保障,文章主要阐述了CRTSⅡ型无砟轨道关键施工技术,为今后同类施工提供技术参考。
Ballastless orbit is an advanced orbital technology in the world today. It overcomes the serious chaff caused by high-speed train operation and frequently repaired lines, improves the safety and comfort, and the train speed can reach more than 200km per hour. The construction of ballastless track basic engineering is the guarantee of high speed train operation. The article mainly expounds the key construction technology of CRTS Ⅱ ballastless track, and provides technical reference for similar construction in the future.
