| 摘 要： | 该文对采用水平转体施工重量达14 000 t的绥芬河独塔单索面斜拉桥静载试验过程进行了阐述。重点介绍了在静载试验中,对各工况下主梁挠度、主塔塔顶变位、斜拉索索力增量、主梁的截面应力进行的测试,并介绍了利用桥梁博士软件建立斜拉桥模型,计算出的各工况下的理论值。文章通过实测值与理论值对比分析表明:结构在试验荷载作用下处于弹性受力状态,主梁、主塔的强度、刚度性能良好,受力状况合理;斜拉索受力合理,疲劳影响小;桥跨结构的偏载效应不明显,横向刚度大;桥跨结构能够满足设计要求。同时还可以看出,该种类型桥梁应用平面程序进行分析计算时,要根据空间分析结果对翼板部分参与工作截面进行适当折减。

| Abstract: | The article sets forth the static load test process of a 14000-t single-pylon single-plane cable-stayed bridge on Suifen River constructed by horizontal turning,focuses introduction on the tests of main girder deflection,main pylon top displacement,tension increment of inclined cable, section stress of main girder under the different constructing conditions in the static load text,and introduces the cable-stayed bridge model established by the bridge doctor software to calculate the theoretical values of th... |
