摘　　要：本文研究了光电图像在堤坝土密实度检测中的应用。首先分析了光电图像对堤坝土密实度的检测原理,建立了光电图像无损检测系统。然后通过检测系统拍摄光电图像并进行图像处理分析,利用漫射理论得到了堤坝土的吸收系数和散射系数。最后建立了堤坝土密实度预测模型,预测结果与环刀法的平均绝对误差为0.074。因此,光电图像在堤坝土密实度无损检测中的应用是可行的。The article studies the application of photoelectric imaging in the detection of soil compaction in dams.Firstly,the detection principle of the compactness of dam soil by photoelectric imaging was analyzed,and a non destructive detection system for the compactness of dam soil by photoelectric imaging was established.Then,the detection system captures photoelectric images and performs image processing analysis,and uses diffusion theory to obtain the absorption coefficient and scattering coefficient of the dam soil.Finally,a prediction model for the compactness of dam soil was established,and the average absolute error between the prediction results and the ring knife method was 0.074.Therefore,the application of photoelectric imaging in non destructive detection of soil compactness in dams is feasible.
