广州猎德大桥主桥是一座独塔、双跨、空间索面的自锚式悬索桥,跨度达480m。为研究该桥的空间主缆在吊索张拉过程中及二期恒载作用下,主缆横向位移和索夹横向偏转角度的变化规律,进行了1:10大比例的全桥模型试验,通过试验数据及空间有限元模型分析,得出一些有益于原型桥梁的施工及设计的结论。
Liede Bridge in Guangzhou city is a single-tower, two-span and spatial cable system self-anchored suspension bridge with the span of 386m. In order to study the varying regularity of lateral displacement of main cable and lateral deflection angle of cable clamp under the procedure of tensioning suspender and the loading of the second phase of dead load. A 1/10 scale down model test of the whole bridge have been carried out. By the analysis of test data and space finite element model, some useful conclusions for the design and construction of the prototype bridge were made in the end.
