摘要
通过对某三跨连续中承式钢桁架拱桥(80+200+80)m进行静载试验,将试验过程中的应变、吊杆增量、挠度测试结果与理论值作了比较,了解了大跨径钢桁架拱桥的整体受力状况,结果表明,该钢桁架拱桥在试验荷载作用下,结构的强度、刚度及吊杆力增量均满足要求,桥梁整体受力性能良好。
The static load test of a three span continuous steel truss arch bridge（80＋200 ＋80 ）m was carried out, in the process of the strain, the increment of the suspender and the deflection test results are compared with the theoretical value. The analysis results show that the strength and stiffness of the steel truss arch bridge under the test load. And the increment of the suspender force meet the requirements, and the whole bridge has good mechanical properties.
