摘要
地裂缝灾害是隐蔽性的地面变形灾害。根据工程实例,总结了裂缝的探地雷达图像基本特征,在此基础上分析了结构开裂、不均匀沉降裂缝、地下介质错动裂缝、滑坡趋势裂缝、崩塌裂缝的探测机理和雷达图像特征。
The underground disastrous hidden cracks constitute a deformation hazard. Based on a case study, the author summed up the basic characteristics of underground cracks in radar images and, on such a basis, analyzed the detection mechanism and GPR images of such structural cracks as the uneven settlement cracks and the medium dislocation cracks in ground floor, the landslide-trending cracks and the collapse cracks.
