摘要
预应力孔道压浆密实度直接影响预应力混凝土桥梁的耐久性和安全性。结合工程实例,探讨地质雷达法和声波散射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,可用于预应力孔道压浆密实度检测。
Prestressed duct grouting compactness directly affects the durability and safety of prestressed concrete bridges.Combined with the engineering example,applications of the geological radar and the acoustic scattering methods in prestressed duct grouting density are discussed.The results show that this kind of nondestructive testing method is accurate,reliable,and it can be used for the detection of prestressed duct grouting density.
