我国客运专线无砟轨道设计中广泛采用WJ 7、WJ 8型扣件,其扣件纵向阻力是进行无缝线路设计的重要参数。为合理确定WJ 7、WJ 8型扣件纵向阻力,设计一种有效的无砟轨道扣件纵向阻力测试方案,简述基本原理,通过在武广客专武汉综合试验段对WJ 7、WJ 8型常阻力扣件及WJ 7、WJ 8型小阻力扣件的纵向阻力现场测试,以及对实测数据的数理统计分析,确定了WJ 7、WJ 8型扣件纵向阻力的合理取值,研究结果可为无砟轨道无缝线路设计扣件纵向阻力取值提供参考。
WJ 7 and WJ 8 fasteners are widely used in the design of ballastless track of passenger dedicated railway in our country. The longitudinal resistance of fasteners is an important parameter for the design of CWR. In order to determine the longitudinal resistance of WJ 7 and WJ 8 fasteners reasonably, an effective test scheme of the longitudinal resistance of ballastless track fastener was designed. The basic principle was briefly described. The WJ 7 and WJ 8 Resistance and WJ 7, WJ 8 small resistance fastener longitudinal resistance field test, as well as the mathematical statistics of the measured data to determine the WJ 7, WJ 8 type fastener longitudinal resistance reasonable value, the research results can be Ballastless track seamless design fastener longitudinal resistance value for reference.
