摘要
高架桥梁减隔震方案通常使用两类减隔震支座,橡胶型减隔震支座和钟摆式支座。高烈度区,高架桥梁的位移能力和结构抗力往往会达到极限。因此,选择何种减隔震支座优化平衡结构位移能力和结构抗力是设计者首要解决的问题。以海口市某大型高架桥项目为背景,通过抗震比选分析、造价分析及使用性能等方面研究比较两种支座对于特定工程的适应性。
The seismic isolation scheme of viaduct is generally two kinds of seismic isolation supports, i.e.rubber seismic isolation support and the pendulum support. In the high intensity area, the displacement capacity and structural resistance of viaduct will often reach the limit. Therefore, it is the first problem to solve for the designers to select what kind of seismic isolation support to optimize and balance the structural displacement capacity and structure resistance. Taking a large viaduct project of Haikou City as the background, the article introduces the adaptations of two supports for the specific projects by the comparison and analysis of seismic resistance, cost and usability.
