Abstract

The finite element and time history analysis method was used to study the dynamic response of a single cabin and folded utility tunnel under seismic conditions, considering the effects of seismic intensity and peak acceleration. The dynamic response characteristics of the utility tunnel assembly connection, joint sealing, and utility tunnel wall were analyzed. The utility tunnel structure's regularity of displacement, stress, and response acceleration were obtained through three-dimensional finite element dynamic time history analysis. The result analysis found that the seismic acceleration response of the overall structure of the utility tunnel is lower than the dynamic response of the soil. The seismic intensity has the greatest impact on the seismic response of the utility tunnel structure, splicing joints, and connecting anchor bolts, and the input angle of the seismic wave has the lowest impact on the seismic stability of the folded utility tunnel.
