The GPS displacement monitoring system has been developed by the authors to assess the stability of large slopes. In order to provide more accurate measurement results, a stochastic smoothing method (the trend model) is applied to displacements measured by the system in this paper. Five types of displacement behavior are supposed as the monitoring results; i. e., 1)static stable state, 2)step displacement, 3)steady rate displacement, 4)converging creep, and 5)tertiary creep. Numerical simulations are conducted for the above displacement behavior types using data measured at a limestone quarry to investigate the applicability of the trend model. It is shown that the trend model can improve the accuracy of the measurement results through those simulations.
