援柬埔寨体育场斜拉柔性索桁结构关键施工技术

Key Construction Technology of Cable-stayed Flexible Cable-truss Structure for Cambodia Stadium

通过理论计算分析和模型试验研究,在施工前合理选择主动张拉索类型,确定斜拉索张拉端位置,优化铺索、展索工艺,研究张拉同步性及成型过程中与结构变形的协调性,对施工过程进行监测,总结形成了斜拉柔性索桁结构的多项关键施工技术,确保结构成型满足设计要求的同时保证了预张力精度。

Through theoretical calculation analysis and model test research,this paper reasonably selects the type of active tension cable,determines the position of the tension end of the stay cable,optimizes the cable laying and spreading technology before construction,studies the synchronization of tension and the coordination with structural deformation during forming, and monitor the construction process,summarizes a number of key construction technologies for the cable-stayed flexible cable-truss structure,which ensure that the structure meets the design requirements and ensure the pretension accuracy.
