土—结构相互作用对隔震体系桥梁的影响

Influence of soil-structure interaction on isolated system bridge

通过ANSYS建立三维实体模型,对未加支座、未考虑土—结构相互作用,加铅芯橡胶支座、未考虑土—结构相互作用,加铅芯橡胶支座并且考虑土—结构相互作用的连续梁桥的三种情况进行对比分析,结果表明土—结构相互作用对结构的动力响应产生不可忽略的影响。

In this paper, we set up 3-D model by ANSYS, do comparative analysis in three cases which are no beating and no soil-structure inter- action, with lead-rubber beating but does not consider the soil-structure interaction, both lead-rubber beating and soil-structure interaction. Ulti- mately it proves that soil-structure interaction on the structure does produce effects what can not be ignored.
