Non-fixed Station Method for Slope Deformation Monitoring with Total Station

The most common used method for safe monitoring of high slope is to set a fixed station point nearby the high slope to monitor the transformation,but the station point is easyto be impacted bythe high slope deformation and construction,and the result took from the point maybe not correct.To avoid the impact and improve the accuracy,a non-fixed station method for slope deformation monitoringwith total station activelyisput forward in thispaper.It discussesthe principle,implementing steps,error analyses and application in engineering project of the method.
