摘　　要：本文针对润扬大桥工程,对U形预应力束作用下索塔模型的三维应力进行了实地测量。用有限元软件如ANSYS、SAP2000、ETABS和数学软件MATHEMATICS进行了计算,并利用概率论、数理统计学、有限元和经典弹性力学理论的方法对所测数据进行了分析对比,得出了一些对工程有益的结论。This paper provides the on-the-spot measure data of three-dimensional stress of cable tower model under U shape pre-stressing force, applies finite element software, such as ANSYS and SAP 2000, ETABS and mathematics software MATHEMATICS to calculate, then it analyzes and contrasts the measure data with the method of probability theory, mathematical statistics, finite element and classical flexible mechanics theory, which reaches some conclusion beneficial for project.
