大型渡槽预应力张拉过程模拟与智能张拉方案设计OA

In this paper,based on the Dongjiacun aqueduct project in Central Yunnan Region,combined with the structural characteristics and design requirements of the aqueduct,a three-dimensional finite element analysis model is established by using ANSYS analysis software,and the prestressed tensioning process of the aqueduct is simulated and analyzed by using cooling method following the tensioning criteria,so as to determine the tensioning scheme.At the same time,in order to effectively control the tensioning scheme during the construction period and improve the construction efficiency and engineering quality of the aqueduct,the intelligent tensioning scheme is designed.The research results can provide reference for the subsequent design of prestressed tension scheme for similar large-scale aqueducts.
