摘要: 岩质边坡的变形破坏主要受地质构造、不利结构面、结构面的充填物及其组合关系等因素的影响;地质构造决定了结构面的发育程度,当边坡发育有软弱结构面或软弱夹层、顺倾不利结构面时,边坡开挖形成临空面后,在软弱面及结构面的空间组合关系作用下,边坡易沿不利结构面向临空面发生变形滑移。通过分析某岩质边坡的变形破坏机理,确定该边坡变形破坏主要由软弱夹层、顺倾不利结构面、连续降雨、坡脚震动等不利因素的共同作用,通过赤平投影分析边坡潜在的变形破坏模式和规模,根据其变形破坏现状和结构面组合反演分析该边坡的稳定系数,并提出针对性的治理措施。

Abstract: Rock slope deformation is subjected to the combinations of geologic structures, structural planes, and filling of structural planes. The geologic structure resulted in the development of structural planes, when weak planes (layers) and inclined planes developed, the slope deformation and the sliding may happen on the exposure face under the influences of those unfavorable factors. By analyzing the broken mechanism of rock slopes in the first place, then confirmed its deformation mainly resulted from the weak layer, the inclined plane, the continuous rainfall and the cutting vibration and so on. The stereographic projection analysis is performed to determine the slope deformation model and scale, finally, slope safety factors are analyzed according to its deformation status and provided targeted treatment measures.

Key words: Rock Slope, Deformation Mechanism, Stereographic Projection, Back Analysis, Treatments
