摘　　要：裂缝是混凝土结构物存在的主要缺陷,基于iTECS-6检测仪器,以混凝土结构的裂缝为研究对象,在检测垂直裂缝的基础上,改进方法,通过类比垂直裂缝的检测原理,提出斜裂缝的检测方法,并给出斜裂缝深度、夹角、延伸长度的计算公式.最后通过制作试件进行了验证.Crack is the main defects of concrete structures. The paper taking the crack of the concrete structures based on iTECS-6 instrument as the research object, first put forward the improvement methods of vertical crack. Then by making an analogy on the detection principle of vertical cracks, we put forward the detection method of inclined crack and given the calculation formula of depth, angle and extension length of inclined crack. Finally, the method was verified by making specimens.
