摘　　要：试验研究是预应力混凝土耐久性研究的重要途径和手段。为了促进预应力混凝土桥梁的耐久性研究,借鉴已有的研究成果,在介绍预应力混凝土结构耐久性研究的重要意义的基础上,分析了国内外试验研究的现状;并重点对国内外进行过的混凝土碳化和氯离子侵蚀试验进行了分类阐述。最后结合现有研究存在的问题对预应力混凝土结构尤其是桥梁结构耐久性试验方法进行了综合评述,并提出了发展方向。Testing is a basic means for the study of PC concrete durability. With a description of the importance of such studies and for their further advance, the existing studies and tests home and abroad are introduced, with emphasis on the classified illustration of the concrete carbonation and chloride ion erosion tests. Finally, a comprehensive comment is made in connection with the problems in the existing studies, especially the method of durability test of the bridge structure, with the proposed development.
