摘要

在收集整理国内外相关资料的基础上，从边坡稳定性分析方法、边坡监测、预测预报方法等方面总结了目前边坡稳定性研究方法及预测预报研究现状，分析露天矿边坡的工程特点，指出当前露天矿边坡稳定性研究存在的问题，提出“边坡岩体渐进损伤破坏是边坡岩体失稳前兆本质特征”这一学术思路，认为边坡稳定性及预测预报研究发展趋势为建立基于微震监测信息反演的边坡岩体内部损伤演化模型，提出露天矿边坡岩体强度参数识别表征方法和动态稳定性评价方法，寻求边坡失稳过程岩体内部“空间”损伤劣化的微震活动性、强度弱化与边坡动态失稳之间的联系，以微震前兆信息和边坡岩体强度储备系数为失稳判据，实现露天矿边坡稳定性动态分析预测

Abstract

Based on the collection and review of the domestic and foreign literatures related to rock slopes

the situations and future development of slope stability analysis and monitoring are summarized in the aspect of methods for rock slope analysis

monitoring and forecast approaches. And especially

the characteristics of open-pit slope are analyzed in detail. The questions existing in the studies of open-pit slope stability are also pointed out. Further

a thought that the progressive damage evolution namely acoustic emission is the nature of rock slope instability is proposed; and the future development of studies of rock stability as well as forecasting methods are given. Firstly

the model which can calculate damage of rock slope from back analysis of the basis of microseismic monitoring data should be built; and the characterization methods of strength parameters of rock mass and evaluation methods of dynamic stability in open-pit slope engineering should be developed. These can give objective evidence to the strength reduction method for rock slope and provide mechanical basis for microseismic monitoring. Secondly

the relationship between microseismic activity

degradation of rock mass strength and slope dynamic instability will be investigated. Finally

precursory information of microseism and safety factor of slope are selected to form combined unstable criterion; and the prediction of rock slope instability and dynamic analysis of open-pit slope stability can be realized
