摘要
由于冻融作用,寒区混凝土支护工程的安全性和稳定性越来越受到重视,而岩石-混凝土界面的强度性能是支护结构发挥功能的关键。文中主要对岩石-混凝土界面冻融损伤演化规律、界面冻融损伤影响因素、界面过渡区(ITZ)强度弱化机理这3个方面进行了综述,分析了目前研究的不足,并提出了改进措施和未来展望,为此方向的相关研究提供一定的参考价值。
Due to the freeze thawing,the safety and stability of concrete support engineering draw attentions in cold regions.Since the strength performance of rock-concrete interface is the key to the function of the support structure,this paper mainly reviews the evolution law of freeze thawing damage at the rock-concrete interface,the influencing factors of freeze-thaw damage at the interface,and the strength weakening mechanism of the interface transition zone(ITZ).The shortcomings of the current research were discussed,the improvement measures of which were proposed,providing the reference for related research in this field.
