An analysis of the kinematics characteristics of the gravel rockfall deposit induced by earthquake

The Wenchuan earthquake caused lots of rockfall in the engineering area,supplying many phenomena of the"natural rockfall tests." The huge gravel rockfall deposit that was caused by the Wenchuan earthquake in the Hongyan holiday resort of Du Jiangyan,Qing Chenghou mountain is analyzed and the focus of this paper is mainly on analyzing its kinematics characteristics.The value of the reach of angle of the rockfall deposit was measured in the site.The reasons leading to the number of the angle large...
