    危岩失稳模式分类研究

    STUDY ON CLASSIFICATION OF DANGEROUS ROCKMASS FAILURE MODES

    • 摘要: 近年来,重庆地区开展的大量危岩防治工作表明,现有的危岩分类方案缺乏统一的定义和内涵,使用中容易出现混淆和争议,同时,还存在危岩无类可归的现象。针对现有危岩分类方案的不足,本文在分析和总结国内主要危岩分类方案的基础上,结合近年来发生的典型危岩崩塌事件的调查成果,对危岩分类问题进行了研究。首先,根据危岩破坏时的初始运动方式,将危岩分为倾倒式、滑移式、错断式、悬挑式、坐落式和坠落式等6类,并根据危岩结构面组合特征及影响因素的差异,进一步细分为11个亚类;其次,对各类危岩的定义、主控结构面位置及发育特征、形成条件及影响因素、变形机理进行了细致的界定和总结,最后,结合典型危岩崩塌实例进行简要的分析和说明。新的危岩分类方案类型全面,定义明确,界限清晰,实用性较强,可以有效地指导危岩勘查评价、监测预警以及防治工作的开展。

       

      Abstract: In recent years, the control of dangerous rockmass in Chongqing region showed that current classification scheme of dangerous rockmass lacked unified definition and connotation, thus easily leading to confusion and controversy, and meanwhile, difficult classification of some dangerous rockmass. Directing at the deficiencies of current classification scheme of dangerous rockmass, this thesis, based on the analysis and summary of domestic chief classification scheme of dangerous rockmass, studied the problem of classification scheme of dangerous rockmass combining with the investigation results of typical accidents of dangerous rockmass slumping happening in recent years. Firstly, according to the initial movement mode of dangerous rockmass failure, it divided dangerous rockmass into such six modes as toppling, sliding, shearing, overhanging, subsiding and falling with 11 subclasses based on differences of combination characteristics of fissure and influencing factors; Secondly, it conducted a detailed definition, location and characteristics of controlling fissure, formation conditions and influencing factors, deformation mechanism, and finally, it analyzed and explained them integrating with typical cases of dangerous rockmass slumping. As the new classification of dangerous rockmass was inclusive, clearly defined and specified as well as highly practical, it could effectively guide the exploration and evaluation, monitoring and forecasting, control of dangerous rockmass.
