| 摘 要： | 分析了当前桥梁挠度测量方法中的激光测量法和成像式测量法的原理,讨论了两种方法的优劣,在综合二者优点的基础上提出了一种激光图像挠度测量的新方法。并在实验室构建出整个测量系统,进行了室外和室内的测试。实验结果表明:在测量环境基本维持不变的条件下(如密封的梁体),系统漂移较小,完全可以满足具有密封梁体的大型刚构桥梁的高精度、大量程的挠度测量要求。 |

| Abstract: | The principles of deflection measurement systems of both laser and imaging are analyzed.With the discussion of their performances,a new method of laser & imaging deflection measurement is provided.The measuring system is designed and tested indoors and outdoors in laboratory.The experment result demonstrates that system excursion is little in the measuring environment-maintaining condition ,and it can be used to measure deflection with high accuracy and large range for large rigid bridges with sealed beam. |
