跨坐式单轨高架车站抗震分析研究

Study on seismic analysis of Overhead Station in Straddle Type Monorail

为研究分析跨座式单轨高架车站的抗震设计,基于跨座式单轨交通的特点,以柳州轨道交通为工程背景,在满足使用功能、规范要求下,分析了单轨高架车站墩柱抗震结果,为单轨高架车站设计提供建议。通过分析得出结论：（1）在多遇地震作用下,桥墩及基础均处于弹性状态,满足规范要求;（2）在设计地震、罕遇地震下支座抗剪满足要求,设计地震下桥墩变形满足要求;（3）在罕遇地震作用下,桥墩均未进入弹塑性状态,各桥墩控制点延性比均小于允许值4.8,满足延性设计要求。

On the analysis of aseismic design of straddle type monorail elevated station, the characteristics of straddle type monorail transportation based on Urban Rail Transit in Liuzhou as the engineering background, to meet the needs of using function, specification, analysis of the monorail elevated station pier seismic results, provide recommendations for the design of monorail elevated station. Research purposes：（1） Under frequent earthquake,pier and foundation are in elastic state, meet the standard requirements;（2） In the design earthquake and rare earthquake shear bearing to meet the requirements of the pier under the design earthquake deformation meet the requirements;（3） Under the rare earthquake, the pier did not enter the elastic-plastic the state of each control point, the pier ductility ratio are less than the allowable value of 4.8, to meet the requirements of ductility design.
