In this study, a small scale experiment of an earth retaining wall was conducted to develop a real-time and full-field noncontact measurement system for earth retaining walls in urban areas. The collapse behavior of the structure was reproduced using a model of an earth retaining wall, and the deformation and displacement of the entire surface of the small scale structure were measured using a 3D image-based digital-image correlation method employing a stereo camera system. The measured displacement was compared with the actual displacement by using high-precision hexapod equipment in the experiment, and the results confirmed a high level of precision.

使用挡土墙的小规模模型测试对3D-DIC非接触式测量系统进行可行性评估

在这项研究中，进行了一个挡土墙的小规模实验，以开发一种用于市区的挡土墙的实时和全场非接触式测量系统。使用挡土墙模型重现了结构的倒塌行为，并使用立体摄像机系统使用基于3D图像的数字图像相关方法测量了小规模结构的整个表面的变形和位移。在实验中，使用高精度六脚架设备将测得的位移与实际位移进行了比较，结果证实了较高的精度。
