广义 Hoek－Brown准则在露天矿边坡稳定性分析中的应用
Application of the Generalized Hoek-Brown Criterion in Stability Analysis of the Open-pit Slope
摘要
Abstract
As a semi-empirical rule for estimating shear strength of integral rock or joint rock mas-ses, the Hoek-Brown failure criterion has been one of the most useful criteria in forecast and cal-culation of Geotechnical engineering.Mechanical parameters of open-pit slope rock were obtained by generalized Hoek-Brown Criterion, and then excavation stability of open-pit slope based on FLAC3 D.Excavation actual situation was verified by calculation results, slope was stable on the whole, local rock and soil may be deformed and failure.Mechanical parameters of slope rock based on generalized Hoek-Brown Criterion can be used to analyze and evaluate slope stability of open-pit extending exploration.关键词
