摘要
本文介绍了适用于大型桥梁的激光图像挠度测量法的测量原理 ,在实验室构建出整个测量系统 ,并进行了室外和室内稳定性实验。实验结果表明该测量系统在室内具有较好的稳定性和可行性 。
The laser & imaging measurement system is considered as a new one for deflection measurement of large bridges.On basis of its measurement principle,to prove its stability,both outdoor and indoor experiments are carried out.It is demonstrated that this system has good stability and feasibility in indoor condition,and it can be used to measure the deflection of large rigid bridges with sealed beam.
