客运专线轨道的平顺性和稳定性分析

本文详细介绍了客运专线铁路的特征——持久的高平顺性轨道,分别体现在路基、桥梁、道床轨道基础设施的高平顺性和稳定性以及路基、桥梁和道床轨道等组合后的平顺性和稳定性上。另外,并详细分析了为保证线路具有持久的高平顺性和稳定性而需在路基、桥隧、道床轨道基础设施以及路基、桥梁和道床轨道等各结构物组合等方面广泛采用的新技术、新结构、新材料、新工艺,及如何应用这些新技术、新结构、新材料、新工艺,从而使轨道达到持久的高平顺性,为修建优质客运专线铁路提供参考。

ANALYSIS OF TRACK REGULARITY AND STABILITY FOR PASSENGER DEDICATED RAILWAY LINE

This paper describes the permanent high regularity track of passenger dedicated line in details, which is one of features of passenger dedicated railway line. Passenger dedicated line requires the high regularity and stability of subgrade, bridge, ballast track infrastructure individually, and also requires the regularity and stability integrally after they get together. This paper also analyses the new technology, new structure, new materials and new technique used for subgrade, bridge, tunnel, ballast track infrastructure and their structures in order to keep permanent high regularity of track, for reference to building passenger dedicated line.
