Characteristics of rock failure in metamorphic rock areas,Korea

摘要

The metamorphic rock ranges in Korea very extensively,which has the unique characteristicsthrough crustal movement and complex metamorphic processes for a long time. So the metamorphic rocks havediscontinuities such as dislocation and fault as well as weak part such as fractured zone and fault gauge. Forthese reasons,there exist great potential of collapses,so it is required great caution to construction and designroads or tunnels in this area. This paper describes the past experiences of slope failure during the constructionof roads at the area of metamorphic complex,especially Gyong-gy gneiss,and analyzes the characteristics ofthe failure patterns in order to prevent from loss of the life and property.
