摘要: 针对露天矿开采过程中高陡边坡破坏形式的分类及损伤机理进行研究。以金川集团露天石英矿边坡监测预警项目为研究背景,运用Matlab软件对位移监测数据进行分析,将边坡的位移场与边坡的破坏形态相结合,对边坡破坏形态进行分类,可分为下滑式、张拉式、侵蚀式、复合式。其中下滑式、侵蚀式破坏发展迅速、破坏程度大,张拉式破坏发展缓慢、破坏程度小。又进一步研究了边坡各破坏形式发生的内部机理,并针对边坡的破坏形式提出了具体的加固措施。

Abstract: The classification and damage mechanism of high and steep slopes in the process of open pit mining are studied.With the monitoring and early warning project of Jinchuan group open pit quartz mine as research background,Matlab software is used to analyze the displacement monitoring data.Combining with the displacement field of slope and the slope failure mode,slope failure is classified into the sliding,the tension,the erosion and the compound.Among them,the sliding and the erosion have characteristics of rapid development and heavily destruction.The tension has slow development and small destruction.The internal mechanism of the slope failure mode is further studied,and the treating measures are put forward according to the slope failure mode.

Key words: Displacement field, Destruction pattern, Destruction of classification, Destruction mechanism, Destruction process
