The fatigue life and relaxation life of bolts affect their service life. Under the joint action of fatigue and relaxation, the connection at the column base is deteriorating. In order to explore the influence of the relaxation of connecting bolts on the fatigue life of high-speed railway sound barrier, bolts with asymmetrical and symmetrical arrangements used for high-speed railway sound barrier at a train speed of 400 km/h are taken as the research objects, and the finite element models of column base bolts are established using ANSYS. The preload is applied by cooling method, positive and negative unit bending moment loads are applied to calculate the stress amplitude of the most unfavorable bolt at the column base under different preloads, and the fitting relationship between the stress amplitude and preload is proposed. Moreover, based on Midas, a whole model of noise barrier is established to analyze the dynamic response characteristics of the barrier structure at the train speed of 400 km/h. The bending moment time history results of column base bolts are extracted to compare the bolt life considering fatigue failure only and the bolt life considering relaxation and fatigue together. Results show that the bolt relaxation will reduce the preload and increase the bolt stress amplitude of bolt base models in both cases of asymmetrical and symmetrical arrangements. In the existing time history calculation of column base bolts, the fatigue life considering the combined effect of relaxation and fatigue is much lower than that only considering the fatigue effect. When the preload is reduced to 55% due to the relaxation, the fatigue effect will occur. The results can provide a reference for designers of connection structures to quantitatively evaluate the bolt life and the maintenance of bolts.
