摘要:
Seismic landslide is an unexpected geological disasters type, of which the formation and development is influenced and controlled by many factors including the earthquake, geology, geomorphology and climate. Its characteristics of uncertainty, ambiguity and complexity make the prediction of its risk is almost impossible via single evaluating factor. Based on the idea of information fusion, this paper proposed a methodology for predicting seismic landslide using the evidence theory which can reflect the comprehensive influences of different factors. Six indices related to the occurrence condition of seismic landslide are taken into account as evidences in the proposed method, including the coefficient of rock weathering, earthquake intensity, fault density, drainage density, relative height and the mountain slope. The basic reliability is objectively constructed using entropy weight grey incidence. The seismic landslide prediction model is built by evidence theory and entropy weight grey incidence. Prediction results of several practical cases show that the method has relatively high accuracy. Because of its reliability and rationality, this method can meet the planning on earthquake resistance and hazardous prevention generally. © 2014 ejge.
