摘要
罗家洞寺崩塌体崖壁危岩倒悬,处于临空状态,随时可能发生崩塌,一旦发生崩塌,新建的罗家洞寺将会再次被摧毁,同时会伤害寺庙工作人员、农户、朝拜人员及游客的生命财产。对罗家洞寺崩塌体的主要形成机理(地层岩性、降雨、地震、节理裂隙)进行分析和论述,同时根据运动学对危岩体发生崩塌时落石的三种运动特征(拉裂式、倾倒式)进行分析,建立落石运动方程,经理论计算与实际发生坠落水平距离相比有误差,因为阻力特性系数在两种状态下不同造成,在此类问题的计算中要结合实际情况加以分析。
Dangerous rock mass that attach to the rock fall cliff of Luojia Dong temple hung upside down and are in free state with collapsing at any time. Once collapsing,the new Luo Jia Dong temple will be destroyed once again and also hurt the lives and properties of the temple workers,farmers,workers,tourists and worship personnel. In this paper,it analyses and discusses its main formation mechanism of loujiadong collapsing body( stratigraphic lithology,rainfall,earthquake,Joints and fissures) and at the same time analyses three kinds of motion characteristics of falling rock in detail when it collapses according to kinematics to establish equations of motion.
