危岩体地质构造及稳定性分析
|
摘要
危岩体的形成、地貌特征、水动力特性及地层变化等因素耦合异变的结果,本论文主要结合盐津县普洱集镇危岩体及陡崖体实际,分析危岩体的形成,危岩成分及稳定性、天然状态的裂隙水压力、暴雨状态的裂隙水压力,可以构成两种组合:(1)自重+裂隙水压力(天然状态);(2)自重+裂隙水压力(暴雨状态);对岩体稳定性进行定性评价和定量评价,并提出防治措施。
The formation of ore mining area, geological landform, hydrodynamic characteristics and formation factors such as changes in coupling change the main results, combined with the Yanjin Pu'er County town of geological ore bodies and steep orebody, analysis of the formation of orebody, the geological composition and the stability of the natural state, fissure water pressure and rainstorm state the fissure water pressure, can form two kinds of combination:(1) weight and fissure water pressure(NATURAL);(2) weight and fissure water pressure(rainstorm); qualitative evaluation and quantitative evaluation on the stability of rock mass, and puts forward prevention and control measures.
