Back analysis of measured displacements in cut slopes

In this paper, a back analysis method for monitoring stability of cut slopes is proposed. The method is based on the displacement measurements taken with the Global Positioning System (GPS). The GPS is an innovative surveying system using artificial satellites. The mechanical properties of rocks can then be back-analyzed from displacements measured by the GPS. In order to assess the stability of cut slopes, the factor of safety is calculated by using the mechanical properties obtained from the back analysis. A practical application of the proposed method for a high cut slope is demonstrated.
