摘要
根据青岛地铁车站墙体病害探地雷达(GPR)检测结果,总结了典型病害的GPR异常特征,说明了病害的延展深度及形式,并通过数值模拟确定了墙体垂向裂缝、环向裂缝及防渗层结构破坏的标准GPR剖面。研究表明,GPR方法对墙体裂缝的延展深度及形式、防渗层破坏检测有较好的效果。
Based on the detection result of Qingdao subway station walls diseases with Ground Penetrating Radar（ GPR）,the paper summarized GPR anomalies of typical diseases,illustrated its depth and extension forms,and determined the standard GPR profile of vertical cracks,ring cracks and using numerical simulation. Studies have shown that,GPR method has a good effect on detecting the depth and extension forms of wall cracks and impermeable layer structural damage.
