针对目前客运专线无碴轨道引入的Ev2路基压实标准,通过对K30与Ev2物理意义、计算公式、检测方法和标准的阐述、分析和比较,澄清K30与Ev2的基本概念和本质区别,提出客运专线无碴轨道路基压实标准的参数选取应满足无碴轨道结构形式的要求。
Aiming at the evacuation standard of Ev2 subgrade introduced into ballastless track of passenger dedicated railway at present, the basic concepts and essential differences of K30 and Ev2 are clarified, analyzed and compared through the physical meaning of K30 and Ev2, calculation formulas, testing methods and standards, Ballastless track subgrade compaction standard parameters should meet the ballastless track structure requirements.
