摘要:

针对公路高墩桥梁立柱垂直度检测问题,提出了采用全站仪自由设站无接触测量方法。该方法能够快速采集桥梁垂直度观测数据,并采用稳健最小二乘法计算桥梁垂直度参数,提高了计算结果的精度和可靠性。工程实际应用案例表明,与传统方法相比,本文方法速度快,检测精度高,可靠性好,为快速解决高墩桥梁垂直度检测提供了新的思路和方法。

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
