摘要
文中结合某大型运动场馆施工实践,对大跨度预应力张弦梁结构施工技术进行了深入探究,对钢索预应力及伸长量进行监测,将其与理论计算值进行对比,钢索张拉力及变形监测值与计算值误差范围均在5%以内,满足设计要求,表明该项目施工技术方案安全可靠,有效保障了跨度预应力张弦梁结构施工质量。
Combined with the construction practice of a large sports stadium,the paper deeply explores the construction technology of largespan prestressed string beam structure.By monitoring the prestress and elongation of the cable,it compares it with the theoretical calculated value.The error range of the monitoring value and calculated value of the cable tension and deformation is within 5%,which meets the design requirements,indicating that the construction technical scheme of the project is safe and reliable.The construction quality of span prestressed string beam structure is effectively guaranteed.
