摘要
阐述了露天矿锚固边坡突变失稳的主控因素，应用突变理论来研究锚固边坡突变失稳的力学过程，建立了尖点突变模型。结果表明，锚固边坡系统发生突变失稳的条件是其系统的总势能，且爆破震动、水动力等因素的作用促使锚固边坡系统发生突变失稳。
The paper describes the major factors of the catastrophic destabilizing conditions of anchored slope in openpit mine.The mechanics of catastrophic destabilization for the anchored slope is studied by means of the catastrophe theory.A catastrophic model on points infection has been instituted.It expresses clearly that the reason for anchored slope to accrue catastrophe is accumulative optential energy in the system.Moreover blasting vibration and hydraulic dynamics impel anchored slope system to accrue catastrophic destabilizing.
