Digital identification of discontinuities and failure mode analysis of high and steep slope in open-pit mine
Rock mass is a composite geological body composed of discontinuities and rock,the existence of discontinuities will reduce the quality of rock mass and the stability of open-pit mine slope to a certain extent.This paper summarizes the common failure modes of slope,takes an high and steep slope in an open-pit mine as the research object,carries out the investigation and statistical analysis of rock mass discontinuities based on the Sirovision system,and obtains 48 discontinuities in the study area.The K-means clustering algorithm was used to obtain the occurrence of three groups of dominant discontinuities,and it was found that wedge failure was possible in the studied area.The calculated safety factor under three different conditions met the standard requirements,indicating that the slope was in a relatively stable state.
