摘　　要：本文在对有缺陷混凝土试件温度场进行研究的基础上 ,通过摄影 ,摄取表面的含水量图像以及不同时刻含水量的变化图像 ,探测用灯光照射而肉眼难于观察的裂纹。并利用ANSYS5 6软件对其实验进行计算 。This paper is based on the research of the temperature field of defective concrete pieces,and the water content images of its surface and the water content variation images in various periods are taken by multi wave band photography to detect split which are hard to discover by eyes under lighting.Then ANSYS 5 6 software is utilized to carry out emulational computation and the results are compared and analyzed.
