The measurement of deflection of a bridge is crucial constituent part in the monitoring of bridges. the majority of existing methods about bridge deflection measurement can not accomplish the real - time and long - range measurement. the ultrasonic method based on connected pipes still has shortage in precision and speed of measurement. to satify the need of deflection measurement of the dafosi bridge of changjiang river, an opto - electronic measurement method is to be used to improve on the method based on connected pipes. furthermore, we will design an automatic opto - electronic deflection measurement system based on connected pipes which can be practised in the long - span bridge
大型橋梁的安全監測具有重要的現實意義，而撓度監測是橋梁監測的一個重要的組成部分。目前現有的許多撓度測量方法還不能實現實時遠程監測，已有的連通管式超聲波法還存在著精度較低，測速慢等不足。針對大佛寺長江大橋撓度測量的需要，在此採用精度較高的光電測量方法結合連通管的優點加以改進。 -
