Abstract: 
subgrade frost heave in seasonally frozen ground can greatly influence the safety and smooth running of high-speed trains and the service performance of track structures. In this study, we used a static model to: (1) investigate track‍–‍subgrade frost heave and develop a dynamic model of vehicle‍–‍track‍–‍subgrade frost heave; (2) explore the transfer relation between subgrade frost heave and track structure deformation; (3) examine the characteristics of interlayer debonding; (4) study the influence of subgrade frost heave on the dynamic response of vehicles in high-speed railways in seasonally frozen regions. A Fourier series was used to fit the frost heave waveform and simulate the behavior of subgrade uneven frost heave using data collected on-site. The results show: (i) The position of frost heave significantly affects the transfer of deformation to a slab track. The largest deformation of the track slab, with the amplitude transfer ratio reaching 20%, was recorded when the frost heave occurred near the joint of the base plate. (ii) At the same frost heave amplitude, long-wave frost heave causes smaller deformation and debonding of the track structure than short-wave frost heave. In the wavelength range of 10‍–‍30 m, the main frequency of the acceleration spectral density was concentrated between 3.5 and 3.7 Hz, with larger frost heave wavelengths producing smaller superposition on the vertical acceleration of the vehicle. (iii) The maximum wheel–rail force occurs when the front bogie passes the frost heave peak, with greater frost heave amplitudes producing greater wheel‍–‍rail force. From these results, we conclude there is a clear need to control the frost heave deformation of the track to reduce the dynamic response of the vehicle and in turn improve train operations.

目的:季冻区路基冻胀对高速列车运行的安全性和舒适性以及轨道结构的服役性能具有较大影响。基于实测数据,本文旨在建立轨道-路基冻胀空间耦合静力学模型和车辆-轨道-路基冻胀空间耦合动力学模型,并采用傅里叶级数进行冻胀波形拟合,进一步探究季冻区高速铁路路基冻胀与轨道结构变形映射关系、层间离缝特征及路基冻胀对车辆动力响应的影响,以期为季节性冻土路基冻胀问题的防治及研究提供依据。
创新点:1.采用傅立叶级数对实测数据进行拟合,并将其作为有限元模型的输入边界条件;2.提出将静力模型的计算结果作为动力模型初始条件的计算方法,简化计算过程,提高计算效率;3.从时域和频域探讨路基冻胀波长和幅值对车体振动加速度和轮轨力的影响。
方法:1.采用傅立叶级数对现场实测数据进行拟合,并将其作为有限元模型的输入边界条件(公式(4));2.通过建立路基冻胀-无砟轨道结构静力与动力模型,分析轨道结构层变形映射关系及车辆动力响应。
结论:1.冻胀位置对轨道垂向上拱变形及层间离缝影响较大;2.轨道结构各层最大垂向变形随冻胀幅值的增大而增大,且几乎呈线性变化;3.路基冻胀波长越大,对车体垂直加速度的影响越小;4.当冻胀波长一定时,车体垂向加速度随冻胀幅值的增加呈非线性增加,且增加幅度逐渐变小。
