- 本文针对混凝土结构施工中具有普遍性的新旧混凝土界面结合问题，联系国内外工程实例和五种提高界面强度的方法，从所用材料性能、施工机具特点等角度进行了综述。
This paper systematically expounds the problems in bonding the interface of new and old concretes which frequently occured in the construction of concrete structures. By combining foreign and domestic practical proect examples, the construction essentials of five different ways to increase its strength as well as the properties of materials and features of the machines and tools used in construction are intro duced and analyzed.1996,1(1): 6-10 收稿日期：1995-8-8分类号：TU528
