摘要
论述了地质雷达和超声法在混凝土质量检测中的原理及方法。分析了混凝土中孔洞、不密实区等缺陷的地质雷达信号特征和声波特性,将地质雷达与超声波法相结合,对桥墩混凝土质量进行全面检测,综合分析测试数据,并通过钻芯法验证了检测结果的有效性和正确性。
An introduction was made on the principle and method of inspecting concrete quality by GPR and ultra-sonic synthesis method.The authors analyze the GPR signal features and acoustic characteristics of concrete defects such as holes and non-dense areas,demonstrate how to conduct overall inspection of bridge pier concrete quality by GPR and ultrasonic synthesis method.Based on comprehensive analysis of testing data,the validity and correctness of inspection results were verified by core drilling method.
