目前混凝土非破损检测方法的应用日益普遍,非破损检测方法的种类也不断的增多,如回弹法、超声法、“超声——回弹”综合法。近来钻芯法又得到应用。在国外拔出法引起了广泛的重视,国内也正在试验室阶段进行研究。不同文献中常仅侧重对其中一种测试方法进行介绍和说明其优点,致使一些读者缺乏全面的比较,其实各种检测方法都有其长处和短处,只有根据不同情况选用最适宜的方法,才能得到满意的测试效果。
At present, the application of non-destructive testing methods for concrete is becoming more and more common, and the types of non-destructive testing methods are increasing, such as rebound method, ultrasonic method, and ultrasonic-rebound method. The core drilling method has recently been applied. Pulling abroad has attracted widespread attention, and domestic research is being conducted at the laboratory stage. Different literatures often focus on the introduction of one of the test methods and explain their advantages, resulting in a lack of comprehensive comparisons for some readers. In fact, various detection methods have their strengths and weaknesses. Only when the most appropriate method is selected according to different situations, can they be obtained. Satisfactory test results.
