混凝土梁桥支承体系使用现状及评估技术进展

摘要

为评价既有梁桥支承体系的技术状况，分别以正交梁桥、斜梁桥以及弯梁桥为分析对象，系统介绍了我国混凝土梁桥支承体系的使用现状，包括典型病害形式、病害形成机制及其对全桥结构性能的影响，阐述了现有支承体系技术状况评价的一些措施方法，提出了今后的发展趋势。%Taking the orthogonal girder bridge, skew girder bridge and curved girder bridge as analysis objects, the using status on the supporting system of concrete girder bridges in China are introduced to evaluate technical condition of supporting system of the existing girder bridge, including the typical disease form, disease mechanism and its effect on the performance of the whole girder bridge structure. Some evaluation methods and means on the existing technical condition of supporting system are discussed.
