Study on comprehensive index method for predicting earthquake-induced landslides

Based on existed research experiences, problems of selection of influence factors and value assignment for single factor in comprehensive index method are further studied and four feasible calculating schemes are drawn up in this paper. By the aid of calculating and analyzing comprehensive index values and making comparison between calculated results and practical performance of natural slopes during historical earthquakes in China, two improved calculating formulas of comprehensive index method for predicting earthquake induced landslides are proposed.
