Abstract
Along with China’s rapid development of urban circle and intercity railway, the National Railway Administration issued Intercity Railway Design Standard in 2015 and corresponding researches on standard simply-supported beam design have been carried out. In this case, to better reflect the applicability and economy of intercity railway and to make full use of the advantages of low cost, convenient construction of T beam, researches on 200 km/h ballastless track simply-supported T beam are conducted with reference to the projects in Pearl River Delta and Wuhan City Circle. On the basis of practical experiences in Delta Zhu River, and Wuhan City Circle, studies on ballastless track simply-supported T beam are dedicated. Finite element analysis of simply-supported T beam model is conducted to calculate the strength and stiffness, and spatial physical model is used for verification. Analysis results show that simply-supported T beam of ballastless track meets the requirements for standard strength and stiffness, effectively reduces the cost, thus can be extensively used in intercity railway.关键词
