Application of Digital Image Recognition Technology in Bridge Load Test
摘要: 基于数字图像相关技术DIC (Digital Image Correlation),建立了箱梁全场变形以及裂纹扩展监测与分析系统,对不同等级加载下箱梁全场变形以及裂纹宽度变化进行了监测试验,得到了准确数据。研究对数字图像相关技术在桥梁工程中的应用具有一定的参考借鉴价值。
Abstract:
Based on Digital Image Correlation (DIC), a system for monitoring and analyzing the full-field deformation and crack expansion of box girders was established, and accurate data were successfully obtained for monitoring the full-field deformation and crack width changes of box girders under different levels of loading. In a word, this study was of a certain reference for the application of digital image relevant technology to actual bridge engineering.
