摘要
通过对1座矮塔斜拉桥主梁竖向变形进行测试分析,以及对该桥主梁下挠偏大的原因进行了分析,并对该桥目前变形所处的技术状况进行了评价,为同类型的桥梁主梁下挠变形的分析与评价提供一定参考。
This paper tests the main girder vertical deformation of an extradosed cable-stayed bridge and analyzes the reasons why the bridge girder down deflection is too large. It assesses the technology condition of the present bridge deformation therefore provides reference for the main girder down deflection deformation analysis of the same type extradosed cable-stayed bridges.
