摘要

通过有效和全面的状况评估，可以确保降低混凝土结构的维护成本。探地雷达（GPR）已广泛用于钢筋混
凝土结构的状态评估，它可以实时提供完全无损的结果。主要用于定位钢筋和确定混凝土保护层厚度。最近，研究
集中在使用 GPR进行钢筋腐蚀评估的可能性。本文概述了 GPR在混凝土腐蚀评估中的应用。文献检索和研究选择方
法用于确定相关研究。首先，此综述显示了实验室研究。之后，介绍了在真实结构上的应用研究。结果表明，实验
室研究并未完全阐明腐蚀过程对 GPR信号的影响。此外，实验室研究结果与现场检查之间没有明确的关系。虽然探
地雷达在结构状态评估方面有着悠久的历史，但需要更多的实验室研究来阐明腐蚀的过程对探地雷达信号的影响。
