In the connection measurement of urban rail transit engineering,the traditional manual connection measurement methods have some drawbacks,such as low work efficiency and easy errors.Through practical research and analysis,this paper proposed a semi-automatic connection measurement method.Based on the"TSDI Multi-observation"airborne software,combined with the Leica total station and the traditional wire-steel method for manual connection measurement,the measurement and data recording were completed through the automatic positioning of the instrument,and then semi-automatic connection measurement was completed.At the same time,utilizing self-designed post-processing software,the data of traverse survey were checked,analyzed,and finally generated,which could be used for rigorous adjustment.A fast and effective method for obtaining high-quality connection measurement results was presented.Using the method in this paper,only 2 surveyors were needed to complete a set of shaft connection survey work,and all the survey work could be completed within 1 hour.Compared to traditional manual measurement,this method improves measurement efficiency by nearly four times,reduces the number of measurement personnel by nearly half,and avoids disadvantages of manual recording errors.
