Aiming at pounding phenomenon at expansion joints of a large-scale aqueduct during earthquakes, a dynamic analysis model considering effects of collision was presented. With time history analysis method of nonlinear seismic responses, pounding effects of adjacent girders at expansion joints on seismic responses of a large-scale aqueduct were studied, and influences of two-sided and one-sided pounding on structural responses were also investigated. The results showed that the pounding changes the response states of the aqueduct to a certain extent, the relative displacements between the girders decrease, but the huge pounding force is harmful to the safe operation of the aqueduct. The results could be a reference for seismic design of large-scale aqueducts.
