路基沉降、上拱、温度条件下轨道结构变形规律仿真数据集

基于有限元方法建立无砟轨道-路基耦合数值分析模型以及车辆-无砟轨道-路基耦合动力学仿真分析模型，在基床表层施加变形以模拟路基沉降/上拱，在轨道板中施加温度场，提取轨道结构各部件受力以及变形特征，分析轨道不平顺、层间离缝以及轨道板、底座板应力数据。

Two coupled models were established using the Finite Element Method (FEM): a ballastless track-subgrade coupled numerical analysis model and a vehicle-ballastless track-subgrade coupled dynamic simulation analysis model. Deformation was applied to the top layer of the subgrade bed to simulate subgrade settlement and uplift, and a temperature field was imposed on the track slab. The stress and deformation characteristics of each component of the track structure were then extracted, and data related to track irregularity, inter-layer gaps, as well as the stress of track slabs and base slabs were analyzed.
