钢板墙混凝土分层浇筑变形研究

Research on Deformation of the Steel Plate Wall in Concrete Layered Pouring

目前,核电工程广泛采用钢板墙混凝土结构,钢板墙在混凝土浇筑过程中会产生永久变形,且很难被修复。为了控制墙体变形,减少对设备安装的影响,文章通过现场试验及ABAQUS有限元分析软件对墙体位移进行了模拟分析,通过改变混凝土分层覆盖时间间隔,计算钢板墙最大位移,优化钢板墙混凝土施工工艺,为后续施工提供参考。

At present,the steel plate wall concrete structure is widely used in nuclear power engineering.The steel plate wall will undergo permanent deformation during the concrete pouring process,and it is difficult to be repaired.In order to control the deformation of the wall and reduce the influence on the installation of the equipment,the displacement of the wall is simulated and analyzed by field test and ABAQUS finite element analysis software.By changing the time interval of concrete layered coverage,the maximum displacement of the steel plate wall is calculated,and the concrete construction technology of the steel plate wall is optimized to provide reference for subsequent construction.
