GEOLOGICAL RADAR SURVEY AND STABILITY ANALYSIS OF ROCK SLOPE IN QIANLING MOUNTAIN
-
摘要: 岩质高陡边坡容易产生边坡失稳、崩塌滑落等地质灾害，其稳定性分析尤为重要。以北京市丰台区千灵山岩质高陡边坡为例，根据地质雷达实测剖面分析得到的岩体内部结构及室内试验获得的岩石力学参数，建立了边坡的地质力学模型，并用有限元强度折减法对千灵山岩质高陡边坡进行稳定性分析，得到了高陡岩质边坡安全稳定系数和潜在滑动面，具有一定的实用价值。Abstract: Stability analysis of the high-steep rock slope focus in research and engineering sectors for a long time because it has been considered as the reason why geological disasters occurred such as slope instability and landslide. Taking the slope in Qianling Mountain in Fengtai District in Beijing as an example, parameters by rock mechanics experiment was obtained by combining with the real internal structure of rock mass which measured by geological radar. Geomechanical model of the slope has been established, and the safety factor was obtained through this model by the strength, and at the same time the whole evolutionary and the location of the critical failure surface can be found directly. Clearly, the applicability of this new method has practical value for the stability analysis of high-steep rock slopes.
