【摘要】：基于對(duì)貴州省遵義市官井邊坡工程地質(zhì)條件、邊坡基本特征及邊坡變形破壞特征分析,可知官井邊坡是在自身不利的條件下,由于斜坡Ⅳ段坡腳開挖到878 m,4#樓內(nèi)側(cè)邊坡坡腳處揭露泥巖夾層導(dǎo)致邊坡沿泥化夾層發(fā)生滑移變形。據(jù)此建立了官井邊坡變形演化機(jī)制的概念模型,結(jié)合三維數(shù)值模擬方法研究了邊坡變形破壞機(jī)制,將邊坡變形演化過程劃分為3個(gè)階段:巖層順層滑移、坡腳應(yīng)力相對(duì)集中階段;邊坡開挖過程中卸荷回彈變形階段;邊坡深切,坡體中順層"壓力拱"形成階段。
[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，
