摘要 以混凝土损伤现象为研究对象,探讨了含裂缝混凝土的损伤机制,并通过相关实验及回归分析,得到混凝土密度与超声波量测纵向波速的关系式,建立了含不同裂缝损伤程度混凝土时,波速与损伤混凝土强度的关系式。 Taking the damage of concrete phenomenon as the research object,the paper explores the damage mechanism of the concrete containing cracks,concludes the formula between the concrete density and longitudinal speed measured by ultrasonic wave,and establishes the relationship between the wave speed and the strength of the damaged concrete for the concrete with various crack damage.
