摘　　要：近年来各地观光栈道的建设方兴未艾,为达到结构成就建筑之美的效果,合理的结构体系、可靠的计算分析和详尽的结构设计,至关重要。为契合泉州大坪山天空栈道建筑体型,选用异形大悬挑钢框架结构,采用梁、板混合单元建立有限元分析模型,进行结构自振特性分析、稳定极限承载力分析、挠度验算、应力验算以及舒适度验算。针对场地岩石地质特征和悬挑结构倾覆力矩引起的支座上拔力,基础类型采用扩展基础+岩石锚杆;鉴于建筑所处的环境,采用耐候钢+金属热喷涂+涂层保护综合防腐法。分析结果表明,结构各项性能均符合相关规范要求,结构安全可靠、体系合理,工程运营以来表现良好。In recent years,the construction of sightseeing trestles in various places is in the ascendant.In order to achieve the effect of structure achieves the beauty of architecture,a reasonable structural system,reliable calculation and analysis,and detailed structural design are crucial.The special-shaped large cantilevered steel frame structure was selected to match the shape of the sky trestle building,and a finite element analysis model was established using beam and plate mixed elements to conduct structural natural vibration characteristics analysis,stability ultimate bearing capacity analysis,deflection check calculation,stress check calculation,and human comfort check calculation.According to the geological characteristics of the site rock and the bearing uplift force caused by the overturning moment of the cantilever structure,the foundation type was adopted spread footing+rock-anchor;In view of the environment in which the building is located,the comprehensive anti-corrosion method of atmospheric corrosion resisting steel+metal thermal spraying+coating protection was adopted.The analysis results show that the performance of the structure meets the requirements of relevant specifications,the structure is safe and reliable,the system is reasonable and the project has performed well since its operation.
