摘要
乌市开发区西山隧道项目引桥在设计时采用双曲球面减隔震支座,有限元软软件分析表明,该支座能够有效降低E1、E2地震力作用下下部结构的水平荷载,在桥梁建设费用不大幅度增加的前提下,可以取得显著的经济效益与社会效益。
Double-way curved sphere surfaced shake reduction-isolation bearing was adopted in the approachspan design of Xishan Tunnel project in Urumqi development zone. The finite element analysis shows that it can effectively reduce Horizon-load on the substructure of the bridge under earthquake and can achieve obvious economic benefits and social efficiency in the premise of no large cost increase.
