| 摘 要： | 在对我国已有地震崩塌和滑坡资料 (简称崩滑 )的研究分析基础上 ,提出适用于我国西部地区地震崩滑的由粗至细、分级预测地震崩滑的方法。 1 )建立地震崩滑最大震中距 ( Rm)与地震震级 ( Ms)间关系的初判准则 ;2 )综合考虑岩性、结构类型、地形、气象、地震等因素对地震崩滑的共同作用 ,并对不同因素的主次作用进行区分和量化 ,建立预测地震崩滑的再判准则。并用 1 996年 2月 3日丽江 7.0级地震引发的地震崩塌和滑坡实例对此预测方法进行了验证。

| Abstract: | Data of ground collapses and landslides caused by historical earthquakes are studied in this paper and a method for grading prediction of the collapses and landslides in West China is suggested. (1) Criteria for defining relationship between the maximum epicentral distance of landslides and earthquake magnitude; (2) A series of factors, such as geological and geomorphologic conditions, precipitation and seismic parameters, are carefully studied, zoned and quantified. The prediction method is examined in the case of Lijing earthquake induced landslides in Yunnan Province. |
