摘要
文章基于三角边长关系式的爬移监测算法,通过几何推导得到爬移量的计算公式,并据此建立曲线弯桥上构爬移的自动监测方法。工程应用实践证明该监测方法监测结果精度高,弥补了传统监测方法中角度测量精度低、所需设备昂贵等缺点,可应用于桥梁健康监控、检测领域,实现高精度、自动化、实时动态地测量曲线连续梁桥爬移量,以判别桥梁健康状况及结构安全。
Based on dislocation monitoring algorithm of triangle side-length relation,this article obtained the calculation formula of dislocation amount by geometric derivation,and then built the automatic monitoring method for curved bridge upper-structure dislocation.The engineering application practice proved that this monitoring method has high accuracy in monitoring results,which makes up for the shortcomings of traditional monitoring methods,such as low accuracy of angle measurement and expensive equipment.It can be applied to bridge health monitoring and detection field,realizing high-precision,automated and real-time dynamic measurement of curved continuous bridge dislocation amount,so as to determine the bridge health status and structural safety.
