摘要
预应力孔道压浆密实度直接影响大跨径预应力混凝土桥梁的耐久性和安全性,结合工程实例,探讨冲击回波法在预应力孔道压浆密实度检测中的应用,结果表明,此类无损检测方法准确、可靠,可用于预应力孔道密实度检测。
The prestressed holes grouting density affects the durability and safely of long span PC bridges. Combined with engineering example, the application of impact echo method in the prestressed holes grouting density of prestressed holes is discussed. The results show that this kind of non-destructive testing method is accurate and reliable. It can be used to detect the compactness of prestressed holes.
