In order to improve the efficiency of horizontal displacement observation and the accuracy of observation data,combined with a foundation pit monitoring project,the Leica NOVA TS50 high-precision measuring robot is used to monitor the horizontal displacement of foundation pit. A monitoring method of horizontal displacement on the top of foundation pit slope is proposed. The accuracy and reliability of the method are analyzed through engineering examples,and the monitoring points are analyzed. The results show that the method presented in this paper is convenient and reliable,and can meet the requirements of horizontal displacement monitoring of first-grade foundation pit.
