摘要
文章以桐梓县狮溪镇机股凼崩塌为研究对象,分析了崩塌的基本特征、影响因素,对危岩的稳定性进行定量计算。同时,以研究区剖面地形作为分析模型,采用Roc Fall软件进行落石轨迹预测分析,模拟分析落石运动轨迹及落点、落石弹跳高度、落石速度及落石能量,为崩塌防治工程布设提供理论依据,也为此类工程地质条件下的崩塌稳定性评价及运动轨迹的分析提供参考。
This paper takes the collapse of Jigudang in Shixi Town,Tongzi County as the research object,analyzes the basic characteristics and influencing factors of the collapse,and quantitatively calculates the stability of the dangerous rocks.At the same time,taking the profile topography of the study area as the analysis model,the RocFall software is used to predict and analyze the rockfall trajectory.The rockfall trajectory and falling point,rockfall bounce height,rockfall speed and rockfall energy are simulated and analyzed.It provides a theoretical basis for the layout of collapse prevention and control projects,and also provides reference for the collapse stability evaluation and rockfall trajectory analysis under similar engineering geological conditions.
