摘要
混凝土预制T梁在我国铁路运营线上使用广泛,对其病害进行准确检测和合理的加固维修,对保证桥梁的安全运营有重要意义。本文对一座预制T梁铁路桥进行了病害专项检查,基于检查结果制定了相应的试验、检测方案,使用无损检测及静、动载试验的方法对结构的安全性能进行了评估。基于对病害成因的分析,制定了有针对性的维修加固方案,以确保结构的安全性与耐久性。本文的研究可以为同类型桥梁的病害处治提供参考。
The concrete prefabricated T-girders are widely used in the railway operation line of China.Therefore,the accurate inspection and reasonable reinforcement to the defects of T-girders are signif icant to the secure operation of bridges.In this paper,based on the defect special inspection of a certain railway prefabricated T-girder bridge,the relevant test detection scheme was developed.The nondestructive,static and dynamic test methods were employed to evaluate the safety performance of the structure.The targeted reinforcement scheme was developed based on the analysis of defect causes to ensure the safety and durability of the structure.This study can provide a reference for the defect treatment of similar railway bridges.
