| 摘 要： | 新老混凝土粘结问题的研究，对混凝土结构的修补和加固具有重要的理论和实际意义。在实际修补工程中具有发展前景的粘结面处理方法———高压水射法处理粘结面，在定量测出其粗糙度后，制成新老混凝土粘结劈拉试件，通过试验研究，得出了不同新混凝土浇筑方向、不同粘结面粗糙度对新老混凝土粘结劈拉性能的影响规律

| Abstract: | The research on adherence of young on old concrete has important theoretical and practical meanings for the repair and strengthening of concrete structures.The water jet method which is prospective for repair engineering is adopted in our test to treat the interface.After the interfacial roughness is quantitatively measured,we make the treated old concrete and new concrete into adhesive splitting tensile specimen.The effect on adhesive splitting tensile behavior is provided with different new concrete pouring direction and different interfacial roughness. |

| Keywords: | adherence of young on old concrete adhesive splitting tensile strength water jet method new concrete pouring direction interfacial roughness |
