【摘要】 岩质高陡边坡的失稳形式包括变形和破坏两种形式,主要失稳形式有松动、蠕动、崩塌、滑动、倾倒、溃屈和拉裂等。不同的地形地貌、地质构造、地层岩性、结构类型、结构面特性的岩质高陡边坡,其失稳形式也不同。岩质高陡边坡的破坏是个复杂的过程,特殊的破坏模式有滑移—拉裂—剪断三段式、阶梯状蠕滑—拉裂式、倾倒变形式、高应力-强卸荷深部破裂式等破坏模式。上述失稳模式可以在时间上或空间上组合,构成组合模式。岩质高陡边坡的影响因素包括自然因素和人为因素两大部分。自然因素中可细分为地形地貌、地质环境特征和大气降水及地下水三个方面;人为因素则主要是指人类工程活动的影响。论文以索风营水电站Dr2危岩体加固治理工程为例,在现场调查的基础上对危岩体的稳定性进行了分析评价,结果表明该边坡已处于濒危状态。该边坡原处治措施可概括为“顶戴帽子”,“腰系带子”,“脚穿鞋子”,笔者在调查分析后对原设计方案提出了一些改进措施,使设计方案更趋于合理。更多还原

【Abstract】 The unstability of the includes distortion and destruction. The main form of unstability includes loose, creep, falling, slip, toppling, buckling and tensile. For different terrain landform, geologic structure, lithology, rock mass structure, characteristic of structural plane of the high steep rock slop , the unstability form is different.The unstability of the high steep rock slop is a complex process and its model includes slip-tensile-shearing, stepped creeping-tensile, dumpage-distortion , high stress-strong discharge deep tensile. In addition, the above pattern may combines in the time or the space, constitution combination pattern.The influence factors of the high and steep rocky slope include two factors: the natural factor and the artificial factor. terrain landform, geologic structure, lithology, rock mass structure, characteristic of structural plane, crustal stress and water. The natural factor can be divided into three parts: terrain landform, geologic environment characteristics, atmosphere precipitation and groundwater; the artificial factor mainly means the influence of human engineering activities.On the basis of site investigation, This thesis takes the reinforced control project of Dr2 dangerous slop of Suofengying as models to study the stability of the high and steep rocky slope. The results indicate that the slope is in imminent unstable state. The original method to deal with this slop can simply summaried as "Wear hat on top", "belt the belt on waist", "puts on the shoe on foot". After analysis, some improvement measures to the original design scheme is put forward, which makes them more reasonable.更多还原
