Comparative Analysis of the Ballast Track Design Standards of High-speed Railway between China and France

Research purposes: The track types of high-speed railway include ballast track type and ballastless track,and each has its own advantages and disadvantages.In France,ballast track is used for high-speed railway and France has the muture experience in laying ballast track of high-speed railway.It is very important to know what is the same and different in the ballast track design standards between China and France when designing the ballast track in China.This paper comparatively analyzes the ballast track design standards for high-speed railway between China and France. Research conclusions: From the analysis it can be seen the most of the product standards are the basically same or equivalent,including the rail standard,fastening standard,sleeper standard and ballast standard,a few of the Chinese standards are higher than the French standards,including the precision of static laying ballast track and the precision of welding joint,and some standards are different in the content and system structure,including track bed standard,CWR standard,installation standard of rail expansion joint and track maintain standard.
