一、砼非破损检测技术在市政系统的应用研究砼非破损检测技术所要解决的根本问题是对已建成的钢筋砼结构以定量的评价。由于在不损坏被检对象的条件下,可以实现结构实体的现场评定,在现代化工业生产质量管理中,成为一种重要的检测手段。特别是近一、二十年来,随着电子、声学、光学、电磁学等技术的发展,测试技术和测试仪器 First, the application of concrete non-destructive testing technology in municipal systems The basic problem to be solved by non-destructive testing of concrete technology is the quantitative evaluation of the reinforced concrete structures that have been built. As the object under the condition of not damaged can be achieved on-site assessment of structural entities in the modern industrial production quality management, has become an important means of detection. Especially in recent one or two decades, with the development of electronic, acoustic, optics, electromagnetics and other technologies, testing techniques and testing instruments
