本文简单介绍了摄影测量技术的原理和特点,以单片梁荷载试验裂缝监测为例,通过桥梁载重的持续增加,变形量不断扩大,来研究分析了摄影测量和人工测量在桥梁裂缝变形监测中数据结果,做回归分析统计,提出摄影测量技术在土木工程方面的优点,结合本次研究,希望可以对摄影测量技术在土木工程变形监测方面的应用起到一定的参考和帮助,提高其应用效果。
In this paper, the principle and characteristics of photogrammetry technology are briefly introduced. Taking the crack monitoring of monolithic beam load test as an example, through the continuous increase of bridge load and the expanding of deformation, the photogrammetry and manual measurement are studied and analyzed in the bridge crack deformation monitoring Data regression analysis and statistics, the advantages of photogrammetry technology in civil engineering are put forward. Combining with this study, we hope some reference and help will be given to the application of photogrammetry technology in civil engineering deformation monitoring to improve the application effect .
