摘要
本文对控制岩体活动的地质因素—岩性、岩体结构、结构面、地应力和水文地质条件等进行了分析。岩性、岩体结构是产生岩体活动的内因。本文将岩体结构划分为六种类型,即整体结构、块状结构、层状结构、碎裂结构、镶嵌结构和散体结构。并对控制岩体稳定性的结构面进行了研究和分类,指出不同结构面对岩体活动的具体影响。通过各种控制岩体活动的地质因素分析,掌握岩体活动规律,对予防灾害性岩体活动,防患于未然有实际意义。
In this paper, the geological agent controlling rock movement—lithologic character, rockbody texture, structural plane, groud stress, hydrogeological condition etc. are discussed. It is necessary to point that lithologiccal character, rockbody texture are internal cause for movement of rockbodies. The textures of rockbodies are divided into six types in this paper, i. e. ensemble, massive, layered, fractured, mosaic and dispersed: meanwhile, the strctural planes of the rock stability are studied and classified. The rock movement has a specific affect on the different strutural planes. By means of the different geological agent analyses controlling movement of the rockbodies, the law of its movement in found out. Therefore, it has a practical significance for the prevention of calamitious movement of the rockbodies.
