摘　　要：由于施工管理的缺失及技术手段的局限性,部分混凝土施工质量问题还未能彻底解决,难免会出现影响工程质量的问题,有些内部缺陷很难在施工时发现,这就需要通过检测技术手段发现其内部缺陷并进行处理,消除质量隐患。目前,还没有成熟的技术手段对钢筋密集大构件复杂节点混凝土内部缺陷进行检测,文章针对混凝土结构内部缺陷常规检测技术优缺点及适用性进行阐述,重点介绍了钢筋密集大构件混凝土结构内部缺陷检测方法,以期为今后类似混凝土内部缺陷检测提供参考。Due to the lack of construction management and the limitations of technical means, some concrete construction quality problems have not been completely solved, and problems that affect the quality of the project will inevitably occur. Some internal defects are difficult to be found during construction, which requires the detection technology to find and deal with internal defects and eliminate hidden quality problems. At present, there is no mature technical means to detect the concrete internal defects for steel-intensive large components with complex nodes. This paper expounds the advantages, disadvantages and applicability of the conventional detection technology of internal defects of concrete structures, and focuses on the detection methods of internal defects of concrete structures with steel-intensive large components, in order to provide references for the detection of similar concrete internal defects in the future.
