摘  要:市政桥梁施工与使用中会出现结构裂缝,裂缝的存在不仅影响外在美观性,还会危及结构安全。文章提出了一种基于受激布里渊散射理论的桥梁结构裂缝检测方法,对工程实例进行裂缝检测实验。并结合裂缝检测结果,分析诱发裂缝的原因及所占比例。研究结果表明,利用受激布里渊散射理论可以高效识别市政桥梁的结构裂缝,为消除结构裂缝对桥梁稳定性的不良影响提供技术支持。Structural cracks will appear during the construction and use of municipal bridges.The existence of cracks will not only affect the external aesthetics,but also endanger the structural safety.This paper proposes a crack detection method for bridge structure based on stimulated Brillouin scattering theory,and conducts crack detection experiments on engineering examples.In addition,the causes and proportion of the inducible cracks are analyzed in combination with the crack detection results.The research results show that using the stimulated Brillouin scattering theory can efficiently identify structural fractures of municipal bridges,providing technical support for eliminating the adverse effects of structural fractures on bridge stability.
