本文介绍了二道河渡槽整体结构模型试验、牛腿三维光弹性试验及牛腿附近槽身二维光弹性试验的试验方法与测试成果,并根据试验成果对大跨度U型槽身斜拉渡槽静力特性进行了分析研究,总结出了斜拉输水结构的设计特点,并对斜拉输水结构纵向计算图式的选取、斜拉输水结构的参数选择、斜拉索的非线性影响、牛腿配筋及牛腿附近局部槽身加强等问题进行了论述。
In this paper, the experimental methods and the test results of Erdahe Aqueduct structural model test, the three-dimensional photoelasticity test of the ventral leg and the two-dimensional photoelasticity test of the trunk near the calf are introduced. Based on the experimental results, The static and dynamic characteristics of the cable-stayed bridge are analyzed and the design characteristics of the cable-stayed transmission structure are summarized. The longitudinal calculation formulas of the cable-stayed transmission structure, the parameter selection of the cable-stayed transmission structure and the nonlinear influence of the stay cables , Beef leg reinforcement and strengthening of the local body near the trunk and other issues were discussed.
