摘要
根据卢氏县地质灾害易发程度等级区划,对滑坡个例进行了分类统计。结果表明,降水对不同滑坡危险等级区域的影响不同。根据前期不同量级降水诱发的滑坡发生概率,拟合出不同地质易发分区的前期降水对滑坡的贡献率指数方程和山体滑坡有效降水量方程,在此基础上建立了卢氏县不同地质灾害易发程度灾害区内山体滑坡预报指标模型。
According to the Lushi County geology disaster easily to send the degree rank regionalization,the classified statistics to a landslide example was conducted.The results indicated that the precipitation to the different landslide dangerous rank region＇s influence is different.According to the earlier period different magnitude precipitation suggestion＇s landslide,the different geology easy to send the district the preliminary precipitation to the landslide technical progress factor exponential equation and the mountain massif landslide effective precipitation equation were fitted,based on it the Lushi County different geology disaster easy to send in the degree disaster area the mountain massif landslide forecast target model was established.
