一、工程概况为了满足高速铁路列车运行的平顺性和稳定性,铁道部组织专家论证,确定京沪客运专线全线采用改进型的博格板式无砟轨道系统(统称CRTSⅡ型无砟轨道系统)。CRTSⅡ型无砟轨道系统优化了预制板间的纵向连接(设定了连接张力),采用先进的数控磨床加工承轨台,研制了独特的高性能沥青水泥砂浆,制定了快
I. Project Overview In order to meet the smoothness and stability of high-speed railway trains, the Ministry of Railways organized experts to confirm that the improved Boge slab ballastless track system (collectively referred to as the CRTS Ⅱ ballastless track system) was established throughout the Beijing-Shanghai Passenger Dedicated Line. The CRTS Ⅱ ballastless track system optimizes the longitudinal connection between the prefabricated slabs (sets the connection tension), adopts the advanced numerical control grinder to process the rail bearing platform, develops the unique high-performance asphalt cement mortar, and develops fast
