以湖南省某高速公路层状岩质高边坡变形体作为典型工程实例,根据地勘成果选择典型断面布置测斜孔对边坡岩体进行监测;对监测数据进行深入分析,提出雨水冲刷和入渗是影响边坡稳定变形的主要因素,岩体内部至少存在两个潜在滑动带,同时监测数据为工程处理措施的制定和实施提供有效指导;通过对边坡开挖过程进行数值模拟,分析边坡开挖导致位移和变形的变化规律。
Taking a deformed rock mass of layered rocky high slope in an expressway in Hunan Province as a typical example, the slope rock mass was selected according to the geological survey result to select the typical cross-section inclined hole to monitor the slope rock mass. The monitoring data were further analyzed, Permeability is the main factor affecting the stability of slope stability. There are at least two potential slip bands in the rock mass. At the same time, monitoring data provide effective guidance for the formulation and implementation of engineering treatment measures. By numerical simulation of slope excavation process, Slope excavation leads to the variation of displacement and deformation.
