结合上海金山既有铁路下顶进公路箱涵工程,介绍以自动全站仪为主的智能导向系统的原理及关键技术.实用表明,该系统在实际施工中具有可靠性强、系统运行稳定、测量精度高的特点,可以在恶劣的施工环境中正常运行.%Automatic real - time guidance measurement is the key to modern construction measurement. Nowa-days, in China the new underground 3D traffic engineering method of pipe replaced by box culvert jacking is used, but the manual measurement can not meet the requirement of real-time monitoring. So a set of Total Station-based intelligent automatic guidance system has been developed thus could achieve the measurement automatically and im-prove work efficiency greatly. The principle and key technology of this intelligent guidance system is introduced. In the same time, combined with successful application of culvert jacking highway in the existing railway project in Shanghai Jinshan, this system proved practical and excellent with higher reliability and accuracy.
