摘　　要：调查CRTSⅡ型板式无砟轨道的病害形式,主要包括,轨道板病害、板间接缝病害、砂浆层病害、支承层病害、侧向挡块病害以及砼封闭层病害。针对各类病害,通过选择适宜的修补材料,采取合理的工艺流程,并对各修补材料和工艺进行效果验证和比较,最终得到最为理想的病害修补方案。修补方案可为今后无砟轨道的修补提供依据及技术支撑。The article studies the defect forms of CRTSⅡ slab-type ballastless track,mainly including,track slabdefect,joint defect between slabs,mortar course defect,supporting course defect,lateral chock block defect andconcrete seal course defect. For various defects,the article finally obtain the optimal defect repair scheme by select-ing proper repairing materials,adopting rational technological processes,validating and comparing the effects of allthe repairing materials and technologies. The scheme can be the basis and technical support for ballastless track repairing in the future.
