摘    要:为获得梁体与轨道的合理制约关系,设计了纵连式无砟轨道锚固体系,并进行了现场试验.通过对锚固体系应力、位移和路基表层压力的监测分析,获得了锚固体系在设计荷载作用下的应力、位移变化及路基表层压力的分布规律.试验结果表明:双柱型主端刺锚固体系满足设计要求,为CRTSⅡ型板式无砟轨道结构更好地应用于客运专线提供了重要依据.

关 键 词:高速铁路  无砟轨道  锚固体系  现场试验  端刺位移

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 ty...
