摘　　要：后张法预应力孔道灌浆质量是影响结构的承载力和耐久性的重要因素之一,在国内外引起了广泛的重视。对此,针对孔道灌浆缺陷的定义、检测方法、评价指标和标准以及验证方法等方面进行了研究,并形成了相应的评价体系。通过对浙江省灌浆密实度地方指南及编制的体系研究,结合十三个工程的实际应用,证明了该体系的有效性和可靠性。The grouting quality of post-tension prestressing duct is one of the important factors affecting the structure capacity and durability,and attracts wide attention both domestically and internationally. Therefore,the definition of duct grouting defects,the inspection and testing method,evaluation parameters and standard as well as the verification method,are studied,and the corresponding evaluation system is formed. Furthermore,through the research of grouting compactness local guide and compiling system in Zhejiang,and combined with the practical applications of more than ten projects,the effectiveness and reliability of the system are proved.
