基于英标规范境外水电站钢桁架桥梁设计

DESIGN OF STEEL TRUSS BRIDGE FOR OVERSEAS HYDROPOWER STATIONS BASED ON BRITISH STANDARD

结合境外水电站1×45m下承式钢桁架桥梁设计实例,介绍了境外水电站桥梁的方案设计选型。在英标规范下,从设计要点、结构构造、荷载及荷载组合等方面对设计过程进行了阐述,并对钢桁架桥梁进行了相应的有限元分析,结果表明结构各项指标验算均满足英标规范要求,以供类似钢桁架桥梁设计提供参考。

Combined with the design of 1×45m through steel truss bridge of overseas hydropower station,the scheme design and selection of overseas Hydropower Station Bridge were introduced.The design process of the bridge under the British standard was described from the aspects of the key points of design,structure construction,load and load combination.the corresponding finite element analysis of steel truss bridge was carried out.The results showed that all the indexes meet the requirements of the British standard.It provides reference for similar steel truss bridge design.
