摘要
针对露天矿边坡的工程实际,对影响边坡稳定的结构面进行实测和统计分析。同时对边坡优势结构面产状进行赤平极射分析,指出倾向于坡内的两组结构面与近似坡面产状的结构面构成不利边坡稳定的结构面组合,在后续开采中应重视这类不利结构面组合诱发的边坡失稳。
Field measurements and statistical analysis were made for the slope structural planes, in connection with slope engi- neering practice. And the occurrences of dominant structural planes were analyzed stereographically. The result shows that a combination of structural planes constitutes disadvantages to the slope stability. So, attention should be paid in the subsequent mining to slope instability induced by such adverse combinations.
