摘　　要：海岸景观带中人行景观桥对连通滨海公园慢行系统和提升项目文旅价值起到重要作用,面对滨海复杂多变的自然环境,桥梁设计还需要综合考虑在海洋环境下结构受力的合理性、通行人群的舒适性。为拓展滨海公园异形桥梁设计思路,以石狮红塔湾观音山人行桥为背景,提出了采用空间异形钢塔斜拉结构的桥型设计方案,利用有限元软件建立全桥有限元模型,分析结构内力、变形、动力特性以及舒适性等,旨在让滨海人行桥梁满足后期实际运营要求。The pedestrian landscape bridge in the coastal landscape belt plays an important role in connecting the slow-moving system of the coastal park and improving the cultural&tourism value of the project.In the face of the complicated&changeable natural environment in the coastal area,the bridge design also needs to comprehensively consider the rationality of the structure under the marine environment&the comfort of the passing people.In order to expand the design idea of the special-shaped bridge in Binhai Park,taking the Guanyinshan pedestrian bridge in Hongta Bay of Shishi as the background,the bridge type design scheme using the space special-shaped steel tower cable-stayed structure is proposed.The finite element model of the whole bridge is established by using the finite element software to analyze the internal force,deformation,dynamic characteristics&comfort of the structure,so as to make the coastal pedestrian bridge meet the actual operation requirements in the later period.
