摘要本工作通过镶嵌方式对开裂混凝土构件进行修复、补强、加固,确保混凝土构件具有不低于开裂前的初始力学性能。镶嵌件用金属或复合材料制成哑铃形状或8字形状,使之中间细长部分贯穿裂缝,两端与原混凝土构件形成嵌固,达到修复、加固作用。试验结果表明,本工作研究的镶嵌式加固方式可明显提高含裂缝的水泥制品的抗折性能,且具有施工方便、可靠性高、成本低廉等优点

Abstract: In this research, the cracked concrete members are repaired and strengthened by inlaying method to ensure that the concrete members have not less than the initial mechanical properties before cracking. The inlay is made into a dumbbell shape or a shape of 8 characters by metal or composite material. The middle slender part of the inlay penetrates through the crack, and the two ends of the inlay are embedded with the original concrete member to achieve the functions of repair and reinforcement. The test results show that the flexural properties of cracked cement products are significantly improved by using this inlaid reinforcement technology in this research. Moreover, this technology has the advantages of convenient construction, high reliability and low cost.

Key words: inlay concrete repair reinforcement strengthening
