摘　　要：采用结构模型试验的相似理论,应用方程分析的方法,推导了相似指标。为了研究分幅联塔斜拉桥的联塔力学行为,对甬江特大桥整个桥塔进行缩尺模型试验研究,介绍了模型试验的结构设计和加载方法设计,建立了求解索力的数学规划模型。The theories of structure experimentation model are presented by combining the equation analysis. Ratio of similitude and similarity criteria are deduced. In order to study on the mechanic behaviour of the joint-pylon of the cabel-styed bridge with separate twin prestress girders and a united twin-pylon. A test for the whole pylon of Yongjiang super-large bridge is made with a scale-down model. The structural design and loading methods for the test model are presented. The mathematical programming model of cable tension optimization is established.
