MOVEMENT OF BRIDGE PIER BY WATER FLOW UNDER FLOOD CONDITION
The foundation of bridge pier is scoured by water flow at the flood condition and this condition makes some changes on the support system of bridge foundation by soil mechanics. Namely, some parts of soil foundation are scoured by water flow and the support force for bridge pier by this part is diminished at flood condition. In this report, the authors show the results of model test on the vibration phenomenon by water flow under the flood condition to compare the feature of vibration between at flood condition and at non flood condition. The natural vibration of bridge pier is so different not only scored effects but also the surrounded water such as the frequency of locking motion of bridge pier becomes lower by added mass of water to compare the one at the non flood condition. Furthermore, the vibration under the water flow shows some periodic motion combining the natural vibration motion of locking. The several results by different support condition of foundation are shown by changing the flow condition.
