Abstract: In order to get the rational relationship of interaction between bridge and rail, an anchored system for longitudinal connected ballastless track was designed, and a field experiment was carried out. The regularities of changes in the stress and displacement of the anchored system and distribution of soil pressure on subgrade under the design loads were obtained through monitoring and analyzing the stress, displacement and soil pressure. The experimental results show that an anchored system with double-pillar type main end thorns meets the demand of design and can be as a fine candidate for the design of CRTS (China railway track system) Ⅱslab ballastless track in high-speed railway.
