According to Chentangping Aqueduct, combined with the large-scale analysis software ANSYS simulation method, this paper analyzes and studies the tension sequence of prestressed tendon of the prestressed concrete aqueduct in the completion period. Based on the prestressed tension scheme of Chentangping, this paper puts forward seven corresponding tension schemes, analyzes and compares the stress and deflection of various schemes and obtains the tensioning scheme which is superior to the designer to provide guidance for the prestressed construction and provide reference for the similar projects.%文章以陈淌坪渡槽为例,结合大型分析软件ANSYS模拟方法,主要对预应力渡槽在完建期的预应力筋张拉顺序进行分析与研究.文章在陈淌坪渡槽设计者提出的预应力张拉方案的基础上,提出了对应的七种张拉方案,并对各种方案进行应力和挠度的分析和对比,得出优于设计者提出的张拉顺序张拉方案,以期能为预应力的施工提供指导,同时希望能为同类型工程提供参考.
