摘　　要：电阻率层析成像(ERT)是新近发展起来的结构健康监测(SHM)中的一种可视性检测技术。结合机敏混凝土的功能特性,从实验方面对这种技术进行了详细研究,分析了激励电压、电极数量、电极尺寸等因素的影响,介绍了测试系统的组成和构件电阻率的测量,系统的成像结果得到了预期的效果。ERT (electric resistivity tomography) is a recently developed visual monitoring technique in structure health monitoring(SHM). Based on the functional characteristics of smart concrete, the technique in experimental aspect is researched in detailed, the influences of the factors such as stimulative voltage, the amount of electrode, the size of electrode and so on are analyzed and the buildup of the testing-system and the measurement of component electric resistance are introduced. The imaging result of the system shows the expected effect.
