Abstract:

This paper proposes a non-contact measurement method which can quickly collect the bridge perpendicularity observation data and solve the problem of verticality detection of high-rise bridges in highways based on the total station free station. This method uses robust least squares method to calculate the bridge verticality parameters to improve the accuracy of the calculation results. The practical application case shows that the new method has advantages of fast speed, high detection precision and good reliability, compared with the traditional methods, which provides a new idea and method for quickly solving the verticality detection of high pier bridge.

Key words: high-rise bridges, verticality detection, non-contact, robust least squares method, free station
