Abstract

<p class="바탕글">The purpose of this study is to analyze shear fracture system using landslide location occurred 1998 at Janghung area For the geological implication, foliation was surveyed and analyzed, and location of landslide, geological structure and topography were constructed into spatial database using GIS. With the constructed spatial database, shear fracture system was assessed by the relation analysis between strike and dip of the foliation and aspect and slope of the topography. We compared strike and dip of foliation and aspectand slope of topography and recognized the typical fracture pattern, strike and dip of joint, that coincided with shear fracture system. The results tells us that foliation ofgneiss has geometrical relation to joint or fault that leading landslide. GIS was used analyze vast data efficiently and the result can be used to assess the landslide susceptibility as important factor.
