【摘要】 危岩体是由多组的结构面组合而形成,在地表风化作用、卸荷作用、重力、地震、降雨等诱发因素作用下处于不稳定、欠稳定或极限平衡状态的岩体。通过对桂林市15座山的326块危岩体发育情况进行实地调查、测绘,得到了几组重要数据,根据危岩体的结构特征和状态特征,将桂林市的危岩体类型分为临空型、倾倒型、贴坡型、孤石型4种基本类型,以白岩山3号危岩体为对象采用极限平衡法对该危岩体稳定性进行了定量验算,综合分析评价了桂林市危岩体的发育特征及稳定性。更多还原

【Abstract】 Dangerous rock masses are rock masses that are in unstable,less stable or limit equilibrium state under actions of surface weathering,unloading,gravity,earthquake,rainfall and so on.They are formed by groups of structure surfaces.In this paper,the authors got some important data through the investigation and mapping on the 326 dangerous rock masses in 15 mountains in Guilin City,and according to the structure and state features of dangerous rock masses,classified them into four types: overhead type,dumping type,posted slope type and isolated type.Then,taking the No.3 dangerous rock mass of Baiyan Mountain as an example,a quantitative calculation was conducted to examine the stability of the rock mass using limit equilibrium method,and the development characteristics and the stability dangerous rock masses in Guilin City was analyzed and evaluated comprehensively.更多还原
