【摘要】 采用超声波法对完好混凝土及裂缝化学灌浆前后超声波波幅和声时进行了比较,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。更多还原

【Abstract】 Ultrasonic 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. Combining with the drilled core appearance quality and the cleaving test,it is explained that using ultrasonic method to test the quality of chemistry injection to crack in concrete is feasible and superior.更多还原
