摘　　要：在对有贯穿空洞缺陷混凝土试件温度场研究的基础上 ,利用试件表面洒水后的影像与试件温度场的关系 ,反映其内部缺陷信息 ,并与有限元计算结果相比较 ,力图探究一种可直接应用于工程实践的快速、大范围、低成本的混凝土无损探测技术。实验结果表明 ,通过混凝土构件的温度场图像分析来判断缺陷的方法能满足上述要求 ,很有发展前景。The temperature field of the concrete specimen with a through-hole defect was studied to look for a way for rapid, large-scale and low-cost nondestructive testing of concrete. The information of inner defect was given by the relationship between the image of the specimen surface besprinkled with water and the temperature field, and compared with the numeric result of finite element method. Experimental results showed that the method was feasible and prospected well.
