随着高速动车组列车的引进和开发及车速的不断提高,列车对轨道的要求也越来越高。普通的双轨无砟轨道对路基的沉降量要求很高,并且在强烈的暴风力作用下,高速行驶的列车容易脱轨,引发严重交通事故。为了满足时速200km以上的动车组列车安全运行,论文汲取了悬挂式单轨交通和双轨无砟轨道的优点,设计了三相无砟轨道,从而保证了高速列车运行的安全性。
With the introduction and development of high-speed EMU trains and the continuous improvement of the speed, the requirements of the trains for railways are also getting higher and higher. Ordinary double-track ballastless track on the subgrade settlement requirements are very high, and in the strong role of the storm, the high-speed train easily derailed, causing serious traffic accidents. In order to meet the safe operation of EMU trains above 200 km / h, this paper draws on the advantages of suspended monorail and double track ballastless track design, designed three-phase ballastless track, thus ensuring the safety of high-speed train operation.
