摘要
针对混凝土结构内部缺陷构建了一种两步诊断评价方法。该方法先采用探地雷达对结构物进行整体评价,再结合冲击回波技术对雷达检测异常区域进行定位,进而对结构内部缺陷类型和位置加以判定。试验研究和工程应用结果表明:该诊断方法在混凝土内部结构缺陷的定性和定位评价中,具有全面、高效、准确的优点,在实际工程检测中取得了良好的效果。
A two-step approach for defects diagnosis of concrete structures is established.The overall condition of the concrete structure is firstly evaluated with ground penetrating radar （GPR）,and the abnormal area detected by radar are located with the impact-echo （IE） scanning technique, then the style and position of the potential defects are diagnosed effectively.The results of test and application demonstrate that： the approach based on GPR and IE techniques has numerous merits in qualitative and location evaluation for defects within concrete structure.It is efficient,accurate and comprehensive.Furthermore, the precision meets actual requirements for engineering purpose.
