从结构受力、经济性、施工技术以及质量控制四个方面对倒T型端刺和∏型端刺进行了系统的分析,结果表明:采用∏型端刺结构,不但优化了端刺的整体受力,而且无论在路基填筑过程中施工端刺还是路基填筑之后施工端刺,均能有效降低工程造价,大大方便施工,缩短施工工期,对于创新和完善我国CRTSⅡ型板式无砟轨道理论体系具有重要的意义。
The results of the system analysis of inverted T-shaped barbed bar and Π-barbed barbed bar from four aspects of structure force, economy, construction technology and quality control show that: Π-type barbed bar structure not only optimizes the whole barbed bar Which can reduce the project cost effectively and greatly facilitate the construction and shorten the construction period. It is of great significance to innovation and improvement of CRTS Ⅱ slab ballastless track theory in our country System is of great significance.
