地质体作为地质灾害的载体,控制地质灾害的类型、规模、方向、变形破坏的方式等。本文以黟县Y027公路溪下村段崩塌为例,从构造、节理裂隙、工程特性等方面分析总结了该崩塌的三种结构破坏模式,其中,节理裂隙的密度、产状,决定危岩体的块度、变形破坏的结构面等;构造褶皱等活动强度决定了岩体的破碎程度,也即灾害的规模;岩体的工程特性反映了岩土体的力学机制及吸水能力,也即抗滑能力的强度。地质体孕育了斜坡变形的主体,在人类工程活动及降雨等外力因素激发下,形成地质灾害。
Geological body as a carrier of geological disasters, geological disasters to control the type, size, direction, deformation and destruction of the way. In this paper, Yixian Yixian Yixian village Xixiacun collapse as an example, from the structure, joint fissures, engineering characteristics of the collapse of the three structural failure modes, including the density of fractures, occurrence, determine the dangerous rock mass The degree of block, the structural surface of deformation and damage, etc. The activity intensity of structural folds determines the degree of crushing of the rock mass, that is, the scale of the disaster. The engineering characteristics of the rock mass reflect the mechanical mechanism and water absorption capacity of the rock mass, that is, The strength of ability. Geological body gave birth to the main body of slope deformation, in the human engineering activities and rainfall and other external factors inspired by the formation of geological disasters.
