Shaking table tests were carried out for Minghe River Aqueduct in SouthtoNorth Water Diversion Central Line Project.Based on the data of the tests，dynamic response characteristics were analyzed for two different design alternatives

which were equal length pile foundation and Unequal length pile foundation.The effect was initially estimated on the dynamic response of pile foundation when circle spray reinforcement was used.And woodrubber model box was objectively evaluated in the tests.It is shown that unequal length pile design alternative is more appropriate than equal length pile.Moreover

circle spray reinforcement can improve the behavior of dynamic response of pile foundation and woodrubber model box is rational and feasible.
