For the displacement monitoring data which is the basis for early-warning and decision-making, there are some problems such as non-uniform period observation, data missing and error rejecting. In this paper, the methods of cubic spline and regression analysis are applied to pretreat the observation data. The results can provide scientific base data for pridiction criterion.
