预测岩土边坡地震崩滑的综合指标法研究

Study on comprehensive index method for predicting earthquake-induced landslides

在已有成果的基础上 ,对综合指标法中影响因子的选取和单因子赋值问题进行了进一步的研究 ,制定了 4个可行的综合指标法计算方案 ;通过对综合指标值的计算分析以及将计算结果与我国历史地震中天然边坡的震害表现进行对比 ,提出了两个改进的预测岩土边坡地震崩滑的综合指标法计算式。

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.
