摘　　要：预应力拉杆拱式渡槽是一种全新的渡槽结构形式,因主拱圈主要承受轴向压力而适用于大跨度结构。采用盈建科软件对胶东调水上承式预应力拉杆拱式渡槽进行整体有限元计算,对各工况下渡槽主拱圈及预应力拉杆进行了结构受力分析,并根据计算结果,对渡槽主拱圈及预应力拉杆进行了承载能力分析。该方法操作简单,结果合理、可信,有利于拱式渡槽设计及复核。Arch aqueduct with prestressed tie rod is a new type of aqueduct structure,it is suitable for large-span structures because of the main arch ring mainly bears axial pressure.In this paper,YJK software is used to calculate the overall finite element of the top supported prestressed tie rod arch aqueduct of Jiaodong Area Water Transfer Project,carried out the structural stress analysis of the main arch ring and prestressed tie rod of the aqueduct under various working conditions,and based on the calculation results,the bearing capacity of the main arch ring and prestressed tie rod of the aqueduct is analyzed.This method is simple to operate,results are reasonable and reliable,it can provide reference for arch aqueduct design and review.
