连续箱梁桥的典型病害检测及分析

Inspection and Analysis of Typical Distress for Continuous Box Girder Bridge

某连续箱梁桥上部结构存在严重的病害情况,为进一步了解技术状况,通过现场检测及静、动载试验,分析病害原因,进行技术状况评价,掌握其实际承载能力,为该桥及类似病害桥梁的维修加固处理提供依据,具有一定的理论和实用价值。

The serious diseases existed on a continuous box girder bridge.To learn more about the actual technology state of structure and the cause of diseases,the on-site inspection and the static and dynamic load tests were carried out,the technical situation of structure was evaluated,the actual carrying capacity was learned for Bridge maintenance and strengthening.This paper presents the right case in that field inspection,crack analysis and technology evaluation for similar bridges.It was a certain theoretical and practical value example.
