摘要
///Great destructive effect of geological disaster such as rockfall and landslide triggered by seismic dynamic action is badly attended. Related research includes following issues. Firstly, statistical analysis of characteristic and triggerig factor of these disasters is discussed. Relation between characteristic of geological disaster and seismic parameters such as magnitude, seismic intensity, focal depth and epicentral distance and slope characteristics such as height, angle, lithology, structure and hydrogeology condition is analyzed by case study. Secondly, formation mechanism and dynamic response characteristic of rockfall and landslide triggered by seismic action is concerned. That is to say, slope failure and following moving process caused by seismic tensile and shear action is discussed. Thirdly, slope stability evaluation and result prediction, especially analysis of their method and technique is studied. Based on this,shortcomings and research prospects are analyzed in detail.
