Research on Properties of Grouting Material for Uplifting Ballastless Track Structure of Operational High-speed Railway
摘要
Abstract
To ensure the properties of the high polymer grouting material to meet the requirements of practical engineering and pollution-free environment, the fatigue, durability and environmental properties of the high polymer grouting material are studied in terms of the fatigue property, chemical resistance, aging durability and environmental performance with systematic anti-fatigue test, durability test and harmful ion content of soaking water test. The properties are verified by engineering application. The results show that the hardened polymer grouting materials has small residual deformation, high dimensional stability, high chemical resistance and aging resistance with over 70% of strength retention. Moreover, the polymer grouting materials embedded long in the ground will not affect the environment. The engineering application indicates that the properties of high polymer grouting materials meet the design requirements and the stability of ballastless track structure is secured effectively.关键词
