摘　　要：随着我国社会经济的迅猛发展,桥梁建设的规模和数量在逐年递增,而大体积混凝土的桥梁结构质量成为各方关注的焦点,对其结构和技术进行检测和评定,是确保工程安全质量的重要环节。无损检测可以在不破坏混凝土结构的前提下检测其病害和缺陷,是目前桥梁检测应用最广泛的技术手段。以某水电站坝顶桥梁检测为例进行探讨,该水电站门桥、交通桥经历了30a的运行,最近几年出现行车震撼感强烈、桥梁梁板开裂等缺陷,相关部门对其结构和外观实施了检测,并对桥梁技术进行综合评定,为桥梁维护提供数据支撑。With the rapid development of China's social economy,the scale and quantity of bridge construction are increasing year by year.The quality of large volume concrete bridge structures has become a focus of attention from all parties.Testing and evaluating its structure and technology is an important link in ensuring the safety and quality of engineering.Non destructive testing can detect diseases and defects in concrete structures without damaging them,and is currently the most widely used technical means for bridge inspection.This article takes the detection of a bridge on the crest of a hydropower station as an example to explore.The gate bridge and traffic bridge of the hydropower station have been in operation for 30 years,but in recent years,there have been defects such as strong driving shock and cracking of bridge beams and slabs.The relevant departments have conducted inspections on its structure and appearance,and comprehensively evaluated the bridge technology to provide data support for bridge maintenance.
