| 摘 要： | 用铅芯橡胶支座隔震装置取代双层矮斜拉连续箱梁桥盆式橡胶支座,采用大型通用软件ANSYS建立该桥有限元模型,分析该隔震桥梁的动力特性和在El-Centro波激励下的地震时程响应,并与非隔震桥梁分析结果进行对比。研究表明:铅芯橡胶支座隔震装置对双层桥梁具有明显的减、隔震效果。 |
| 关 键 词： | 双层桥 矮斜拉 连续箱梁 铅芯橡胶支座 隔震 |

| Abstract: | This paper makes a prospective research on technology of seismic isolation.Lead rubber bearings(LRB) which is used as a seismic isolator-LRB is introduced to replace the pot neoprene bearing,and then a spatial computational model is built with the software ANSYS.The dynamic property and time-history seismic response under the excitation of El-Centro wave are analyzed and compared with the results of the non-isolated bridge.The research shows that the reduction and isolation efficiency of the LRB is obvious ... |
| Keywords: | double decked bridge partially cable-stayed continuous box-girder LRB seismic isolation |
