【摘要】：基于对贵州省遵义市官井边坡工程地质条件、边坡基本特征及边坡变形破坏特征分析,可知官井边坡是在自身不利的条件下,由于斜坡Ⅳ段坡脚开挖到878 m,4#楼内侧边坡坡脚处揭露泥岩夹层导致边坡沿泥化夹层发生滑移变形。据此建立了官井边坡变形演化机制的概念模型,结合三维数值模拟方法研究了边坡变形破坏机制,将边坡变形演化过程划分为3个阶段:岩层顺层滑移、坡脚应力相对集中阶段;边坡开挖过程中卸荷回弹变形阶段;边坡深切,坡体中顺层"压力拱"形成阶段。
[Abstract]:Based on the analysis of the engineering geological conditions, the basic characteristics of the slope and the deformation and failure characteristics of the slope in Zunyi City, Guizhou Province, it can be seen that the slope of Guanjing slope was excavated to 878 m under the unfavorable conditions of itself, because the foot of the slope 鈪，
