地震动力作用触发的斜坡崩、滑地质灾害因其巨大的致灾力引起了广泛关注,其研究主要集中在:①地震触发斜坡崩滑灾害特征和影响因素统计学分析,即从典型地震触发的大量斜坡崩滑灾害实例研究入手,从统计学角度分析地震崩滑灾害发育特征同地震参数(地震震级、地震烈度、震源深度、震中距等)和斜坡体特征(坡高、坡角、岩性、构造、水文地质条件等)之间的关系;②地震触发斜坡崩滑灾害的形成机制和动力响应特征研究,即分析地震波产生的拉压和剪切作用对斜坡体的影响及在这种作用下斜坡体发生的破坏和运动过程;③地震作用下斜坡稳定性评价和致灾预测研究,主要是评价、预测方法和技术的类别及特征。基于此阐述了该研究中存在的问题和今后的研究趋势。

Great destructive effect action is badly attended. Related of geological disaster such as rockfall and landslide triggered by seismic dynamic 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 studyed. Based on this, shortcomings and research prospects are analyzed in detail.
