摘　　要：在研究岩浆岩和变质岩特点的基础上,根据岩浆岩岩体结构体的大小、有无缓倾的结构面及岩浆岩散粒状边坡岩体的特征,将岩浆岩边坡岩体结构划分为4大类7个亚类;根据部分正变质岩边坡岩体结构与岩浆岩边坡岩体结构类似,部分副变质岩中发育的板理、千枚理、片理类似沉积岩中的层理,以及边坡岩体具有似层状岩体结构的特征,把变质岩边坡岩体的结构划分为5大类11个亚类。岩体结构的划分为边坡稳定性研究、边坡病害治理及其工程效果评价提供了依据。Based on detailed considerations on the characteristics of rock mass in slopes of magmatic and metamorphic rocks, 4 categories including 7 subcategories were classified in detail for rock mass structures in slopes of magmatic rocks according to not only rockmass size of magmatie rocks and whether structure joints exist or not but also the characters of magmatic rocks with loose slopes. Similarly, 5 categories including 11 subcategories were classified for rock mass structures in slopes of metamorphic rocks. The classification of the rock mass structures in this paper offers a basis for the study of slope stability, the control of slope failures, and the evaluation of slope engineering.
