Abstract
In this research, case studies considering tunnel interface were conducted for zoning the ground into spatial area having similar geotechnical characteristics and estimating geotechnical properties for each area. The site for analysis consists of banded biotite gneiss, biotite schist and granite gneiss with spatial non-homogeneity, and for that reason weathering and fault zone were distributed with large scale. It's important thing to consider spatial ground zone and their geotechnical properties properly into stability analysis at design and construction stage. Also, in this studies, these analysis works are very useful for further decision making process by stability analysis.
