【摘要】 西南是我国地震滑坡多发区。根据汶川地震、庐霍地震、松潘-平武地震和昭通地震诱发的典型地震滑坡的调查和资料分析,结果表明不同地震诱发的滑坡坡度频率分布存在一定的差异,而地震滑坡与降雨滑坡坡度频率分布的差异较大,其分布规律遵循Logistic分布。通过Logistic分布函数分别建立了典型地震滑坡和区域地震滑坡坡度分布的定量评价方法,可为滑坡影响因子的定量计算、评价提供参考。更多还原

【Abstract】 Study of data on seismic landslides caused by Wenchuan Earthquake,Luhuo Earthquake and Songpan-Pingwu Earthquake indicates that seismic landslide had caused the numerous personnel casualties and directly destroyed facilities and that frequency distribution of landslide gradients was differences between seismic landslides and rainfall landslides.The frequency distribution of seismic landslides follows the Logistic distribution.The calculation and evaluation methods for gradient distribution of typical seismic landslide and regional seismic landslide were put forward.更多还原
