摘要
对水下混凝土裂缝的各种现有修补方法作了概述,现行最为常用的方法有表面封闭技术和深入裂缝内部的全面性修补技术,其中全面性修补又包括水下灌浆技术和水下裂缝自修复技术。仿生自愈合混凝土的裂缝修复技术与常用方法的本质性差别显示了修补技术的智能化发展方向。由于仿生自愈合技术的不成熟以及水下修补的特点,水下仿生自愈合混凝土有待进一步研究。
Summary of existing methods for repairing cracks of underwater concrete has been made and currently the ordinary methods are superficial sealing treatments and essential treatments,including underwater grouting technology and underwater self-healing technology.The difference between the biologically intelligent concrete and those ordinary methods shows the development trend towards intelligence for repairing cracks.Because of the technological immaturity of biologically intelligent concrete and the water-saturated characteristic of underwater concrete,the further research of underwater concrete with biological intelligence is urgently needed.
