摘　　要：智慧岛景观桥是衢州市高铁新城内的两座人行及非机动车桥,两座桥梁主桥均采用异型变高半穿式桁架结构,西桥主桥跨径为(60+160+35)m,东桥主桥跨径为(45+160+35)m。介绍了前期桥型方案比选和总体设计情况,并以东桥为例详细介绍了结构设计。桥梁整体静力计算、稳定性分析和动力分析的结果表明该桥设计合理、满足规范要求,可为同类半穿式桁架结构桥梁设计与计算提供参考。The Smart Island Landscape Bridge is two pedestrian and non-motorized vehicle bridges located in the high-speed rail new town of Quzhou City.The main bridges of both bridges are the special-shaped variable height semi-through truss structure bridge.The main bridge span of the west bridge is(60+160+35)m,and the main bridge span of the east bridge is(45+160+35)m.Compared with bridge type schemes and overall design in the early stage,and taking the east bridge as an example,the structural design is introduced in detail.Through the overall static calculation,stability analysis and dynamic analysis of the bridge,the results show that the bridge design is reasonable and meets the requirements of the specifications,which can provide reference for the design and calculation of similar semi-through truss structure bridges.
