摘要
采用超声波法对完好混凝土和裂缝混凝土在其裂缝修补前后的超声波波幅、声时进行了比较,分析了波幅和声时的对比关系,结合取芯芯样的外观质量和劈裂试验,说明了使用超声波法检查混凝土裂缝灌浆质量的可行性和优越性。
Uhrasonic method was adopted to study the intact concrete and concrete with crack which chemically injection was done or not. It was compared with wave amplitude and propagating time and their relationship on crack. Having tested that drilled core appearance mass and cleave the core, it has explained feasibility and superiority using ultrasonic method to test the mass examining that the quality of chemistry injection to crack in concrete.
