利用Midas软件建立桥上CRTSⅡ型板式无砟轨道系统台后“端刺+摩擦板”锚固体系的有限元模型,分析了在不同长度带肋摩擦板和无摩擦板两种工况下端刺顶部水平位移,同时对运营期间京津城际铁路台后锚固体系进行了现场调查,结果表明倒T形端刺和摩擦板等组成的台后锚固体系满足变形要求,台后路基及无砟轨道结构稳定。
Using finite element model of Midas software to establish the anchorage system of CRTSⅡ slab ballastless track system on back of bridge, the paper has analyzed the effect of spur piercing under different conditions of ribbed friction plate and frictionless plate The horizontal displacement at the top of the platform and the on-the-spot investigation on the post-station anchoring system of Beijing-Tianjin inter-city railways during the operation period. The results show that the anchoring system composed of inverted T-shaped end spikes and friction plates meets the requirements of deformation and the abutment subgrade and ballastless track stable structure.
