摘要
钢筋混凝土结构的无损检测一直是工程界普遍重视的问题,也是保证大型建筑结构安全服役的关键.在用雷达技术和超声波CT技术对钢筋混凝土梁无损探伤的基础上,分别对各自的成像效果进行分析和对比,图像分析的结果表明,雷达波能较好地检测到混凝土中的钢筋,而超声波CT成像技术对分析混凝土内部的密实度较有利.基于图像直观明确的特点,将图像技术应用到混凝土结构的检测上做了有益的尝试.
How to make non-destructive testing on concrete structure containing rebar is the prevalent problem in civil engineering field, which is regarded as the difficulty to ensure the safety and durability of large concrete construction. In order to get a better non-destructive estimating, Radar and ultrasonic tomographic techniques are utilized to test concrete. The images are analyzed respectively and the comparison result shows that radar is good for detecting rebar in concrete while ultrasound CT technology is suitable for hollow inspecting. Because of clarity character of images, the imaging techniques are applied to concrete nondistructive testing.
