文章以某高速公路装配式结构简支转连续体系T梁桥为例,对桥梁运营中出现的主梁滑移、桥墩偏移、支座功能失效等病害归纳汇总和成因分析。通过桥墩纠偏、梁体复位、更换支座等方法来恢复支座正常使用功能、恢复梁体自由变形、防止梁体在运营过程中发生落梁。从新建桥梁设计和施工的角度出发,结合现行相关规范,对发生上述病害的桥梁进行成因分析、加固设计,以期给桥梁设计单位、桥梁施工单位以及桥梁管养单位在桥梁设计-桥梁施工-桥梁运营管养的各个阶段提供参考,从而尽可能减少上述桥梁病害的发生,保证桥梁安全舒适的运营。
Taking a T-girder bridge with simple structure and simple structure as an example, this paper summarizes the genesis and causes of main girder slip, bridge pier deflection and bearing function failure in bridge operation. Rectification by the pier, the beam body reset, replacement of bearings and other methods to restore the normal use of the support function to restore free deformation of the beam body to prevent the beam body in the course of operations to fall off the beam. From the point of view of new bridge design and construction, combined with the current relevant norms, this paper analyzes the causes of the above-mentioned bridges and reinforces the design to bridge design units, bridge construction units and bridge custody units in the bridge design - bridge construction - bridge Operation and management of various stages of reference to provide, so as to minimize the occurrence of the above-mentioned bridge diseases, to ensure the safe and comfortable operation of the bridge.
