大型预应力混凝土矩形渡槽槽身结构型式研究
Research of Large-scale Prestressed Concrete Rectangular Aqueduct Body Structure Type
摘要
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.关键词
