摘要
为保障碾盘山水利枢纽泄水闸闸墩门机大梁支撑桁架运行安全,采用SAP2000三维结构整体性能分析与设计计算软件对支撑桁架和锚固系统进行计算,混凝土浇筑施工时,分别就桁架Ⅰ型和桁架Ⅱ型、单个钢牛腿强度、刚度和稳定性等问题进行计算并分析比较结果。结果表明,大梁支撑桁架及钢牛腿等强度、刚度和稳定性满足施工要求。
In order to ensure the safe operation of the supporting truss of the girder of the portal crane of the sluice gate pier of Nianpanshan water conservancy project,the SAP2000 three-dimensional structure overall performance analysis and design calculation software is used to calculate the supporting truss and anchoring system. When the concrete is poured,the strength,stiffness and stability of a single steel corbel are calculated,analyzed and compared between type-Ⅰ and type-Ⅱ trusses. The results show that the strength,stiffness and stability of the supporting truss of the girder and the steel corbels can meet the requirements of the construction.
