摘要
针对中小跨径桥梁的挠度测量,研究一套基于数字散斑相关方法的测量系统,并通过实桥试验,比较该系统与全站仪的测量结果,验证数字散斑相关方法在中小桥梁挠度测量中的可行性。
Aiming at the measurement for deflection of medium and small-span bridges,this paper studies a set of measurement system based on digital speckle correlation method and compares this system with the result of measurement by total-station instrument via the test of practical bridges to verify the feasibility of digital speckle correlation method in measurement for deflection of medium and small-span bridges.
