摘　　要：桥梁一旦发生损坏,短时间内无法恢复,甚至会导致生命财产损失。针对该现象,论文对桥梁的抗震性能进行了分析。通过实际工程表明桩土作用会增加桥梁抗震性能;不同地震力作用下,桥墩内力和位移会发生不同变化。Once the bridge is damaged,it cannot be restored in a short period of time,and even lead to the loss of life and property.In view of this phenomenon,the seismic performance of the bridge is analyzed.Through actual engineering,it is shown that the action of pile soil will increase the seismic performance of the bridge;under the action of different seismic forces,the internal force and displacement of the pier will change differently.
