Automatic monitoring of horizontal displacement in deep foundation pit

This paper aims to introduce the free stationing and its accuracy analysis in horizontal displacement monitoring of deep foundation fit, as well as discuss the feasibility and efficiency of using free stationing to maintain a horizontal displacement automatic monitoring, which is based on the automatic deformation monitoring of Georobot. It also shows that such kind of system can achieve an automatic, precise and efficient horizontal displacement monitoring, and can provide timely and reliable monitoring data for the safety construction through the application of specific project cases.
