摘要
混凝土构筑物质量缺陷大多具有较大的隐蔽性。针对地质雷达法、超声横波三维成像法、单面声波平测法3种常用检测混凝土结构缺陷物探方法进行介绍,重点论述了超声横波三维成像技术。以观音滩水库溢洪道混凝土裂缝及坝面板底脱空检测项目为例,分析各类物探数据对于混凝土不同类型缺陷异常反应典型特征,采用取芯法对解译成果进行验证,效果良好。
The quality defects of concrete structures are more problematic. This paper discusses three methods, including geological radar method, ultrasonic transverse wave three - dimensional imaging method and single -side acoustic wave measurement method, which are commonly used to detect defects in concrete structure, and emphatically introduce three -dimensional ultrasonic wave imaging technology.

This paper dis- cusses three methods, including geological radar method, ultrasonic transverse wave three -dimen- sional imaging method and single - side acoustic wave measurement method, which are commonly used to detect defects in concrete structure, and emphatically introduce three -dimensional ultra- sonic wave imaging technology.
