摘要:
结合南水北调中线双洎河渡槽探讨大型预应力混凝土矩形槽槽身结构型式.采用平面结构力学法和三维有限元法相结合的方式对槽身结构方案进行配筋和混凝土应力计算,并对槽身混凝土应力、施工方案和投资进行比较,得出大型预应力混凝土矩形渡槽宜采用边墙和底板均无肋的板式结构,此种结构混凝土应力更均匀、利于抗裂,亦便于机械化施工,为今后大型预应力混凝土矩形渡槽的设计施工提供参考.
Abstract:
Based on Shuangji River aqueduct in the middle route of South-to-North Water Transfer Project,the structural type of large prestressed concrete rectangular aqueduct was examined.Plane structural mechanics method and 3d finite element method was used for calculation of reinforcement and concrete stress.By comparing the concrete stress,the groove construction method and the investment of different modes,it was concluded that slab structure of unribbed side wall and bottom plate was the appropriate structure for large-scale prestressed concrete aqueduct,and the structure of which had more balanced concrete stress,concrete cracking resistance,and was more convenient for mechanized construction.This paper provided a reference for the design and construction of large prestressed concrete rectangular aqueduct.
