In　order　to　improve　the　seismic　performance　of　continuous　bridge,　the　acceleration　activating　locking　dowel　was　designed　to　be　installed　between　the　sliding-piers　and　beams,　which　would　restrict　the　relatively　displacement　between　the　sliding-piers　and　beams　under　strong　earthquakes　and　help　the　fixed　piers　to　collaboratively　bear　the　longitudinal　seismic　force,　that　is　the　damping　mechanism　of　the　continuous　bridge　locking　dowel　system.The　traveling　wave　effects　may　result　in　the　difference　of　pier　top　acceleration,　then　the　lock　timing　of　each　pier　is　different.To　clarify　the　influence　of　traveling　wave　effect　on　damping　effect　of　continuous　bridge　locking　dowel　system,　the　large　mass　method　was　used　to　study　the　influence　of　traveling　wave　effect　on　seismic　response　of　continuous　bridge.Results　indicate　that　the　traveling　wave　effects　has　certain　impact　on　the　damping　effect　of　continuous　bridge　locking　dowel　system,　but　the　seismic　response　of　sliding-piers　can　be　significantly　increased　in　consideration　of　the　traveling　wave　effect.Besides,　the　influence　to　the　side　piers　is　more　evident　than　middle　piers,　and　the　influence　level　to　continuous　bridge　is　affected　by　the　four　factors,　i.e.value　of　apparent　wave　velocity,　the　relative　position　of　the　sliding-piers　with　the　fixed　pier　and　the　earthquake　location,　activation　status　of　the　sliding-piers　under　earthquake.If　the　traveling　wave　effect　is　ignored,　the　unfavorable　effect　on　structural　safety　reliability　analysis　of　continuous　bridge　locking　dowel　system　are　likely　to　be　caused　after　the　earthquake.　©　2020,　The　Editorial　Board　of　Journal　of　Basic　Science　and　Engineering.　All　right　reserved.
