%X 由于重载铁路隧道基底结构因列车的反复长期性动荷载的施加，导致基底结构大量出现疲劳损伤的现象，严重危及列车安全。介绍疲劳寿命的预测方法，详细说明每个疲劳寿命预测方法的优点与不足，讲述疲劳计算原理，引入专业疲劳计算软件，可用于不同因素条件下的基底结构的寿命计算。<br />
Due to the repeated long-term dynamic load of the train, the base structure of the heavy haul railway tunnel has a lot of fatigue damage, which seriously endangers the safety of the train. The fatigue life prediction methods are introduced, the advantages and disadvantages of each fatigue life prediction method are explained in detail, the fatigue calculation principle is described, and the professional fatigue calculation software is introduced, which can be used to calculate the life of the base structure under different factors.
