High-speed railway represents the developing direction of railways in the world. Systematically researching the basic theories, engineering construction and operation practice of high-speed railways in China has great significance to speed up the construction of world-classhigh-speed railway sandrealize the strategic target of“going-out” for China' s railway technology.Based on alarge quantity of the oretical and testing researches and construction practices, this paper systematically researched the main design standards of high-speed railways in China,
and the comprehensive testing results of Beijing-Tianjininter-city railway and Wuhan-Guangzhouhigh-speed railways how the main technology standards can satisfy the safety and stability requirements of 350 km/h railways and the quality of lines reaches world advanced level.
