无碴轨道结构设计的关键在于强度、横向稳定性、刚度均匀性、减振性和耐久性。
ballastless track on soil subgrade has been already widely used on high-speed railway abroad, but it is just at the starting stage in China.土质路基上的无碴轨道在国外高速铁路上已得到广泛应用,而在我国却处于刚起步阶段。
The interference of the traction current is one of the important subject in the major of railway signal. The use of ballastless track will influence it's condition.牵引电流干扰是铁路信号专业的一个重要课题,采用无砟轨道之后会给轨道电路抗牵引电流干扰带来一定的影响。
