单箱多室连续梁桥病害能力分析及承载能力评估

Analysis on Disease Ability and Evaluation on Bearing Capacity of Single-box Multi-chamber Continuous Girder Bridge

摘要:

部分预应力混凝土桥梁经过多年的运营，梁体的承载能力大不如从前，主要病害是箱梁混凝土梁体出现不同性质的裂缝。裂缝的形成在实际工程中由于施工隐患、日常养护不及时导致多个因素综合作用的结果。

Abstract:

After many years of operation, the bearing capacity of some pre-stressed concrete bridges is not as great as before. The main diseases are the miscellaneous cracks in the concrete beam body of box girders. The formation of cracks in practical engineering is the result of combined action of many factors due to the hidden dangers of construction and the untimely routine maintenance.
