摘要
在实际的混凝土结构检测中,斜裂缝是常见的,垂直裂缝只是特殊情况。为研究平测斜裂缝的新方法,设计了一个理论模型,推导出了计算斜裂缝倾角和延伸长度的公式。并制作了斜裂缝模块进行检测实验,验证了理论模型和计算公式的合理性。
In actual ultrasonic testing of concrete structures,the inclined cracks are usual,and vertical cracks are just the special cases. To research the single plane detecting of ultrasonic testing method for the concrete structures with inclined crack,an academic model was designed,and a formula for calculating the obliquity and length of inclined crack was derived. Then a concrete model with inclined crack was made for the ultrasonic testing experiment,this experiment validated the rationality of the academic model and formula.
