Abstract

In this paper, static GPS is used in real-time monitoring of the displacement variation of landslide hazard, GPS deforming monitoring data resolving and the scientific data required by observation conclusion analysis is provided. As the major criterion of early warning and decision-making, some problems are existed in the original monitoring data such as the non-uniform, discontinuity of period observation, and error rejects due to the observation. The characteristics of the original data is analyzed and the original data is pretreated using the principle of least square method, scientific basis data is provided for prediction criterion. The GPS monitoring scheme is chosen based on the practical geological characteristics and the main causes of disasters in the disaster region.
