摘要
The huge gravel rockfall deposit that was caused by the Wenchuan earthquake in the Hongyan holiday resort of Du Jiangyan, Qing Chenghou mountains 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. By the analysis, 1/4 of the number of the whole rock blocks (＞ 1 m3) were trapped at the turning of the gravel on average. The results show that it is of great significance to research the kinematics of the rockfall deposits and to decrease the rockfall hazards by analyzing the characteristics of distribution and migration of the rockfall deposit caused by natural forces.
