Abstract
A two-dimensional finite differential model is established to find the variation of displacements and stresses of culvert components. The time-history analysis is performed and a wide range of parametric studies are carried out to investigate the influences of height of embankment, ground acceleration and the propagation angle of seismic wave on the responses of the junctions between the culvert components under seismic loads. The results show that the horizontal displacements, the peak values of internal forces under seismic loads increase considerably and nonlinearly with the increases of the height of embankment. The peak values of stresses are sensitive to minor variations of acceleration. And the stresses in the culvert structure are reduced, when the propagation angle of seismic wave increases.
