THE METHODOLOGY ASSOCIATED WITH THE STABILITY ANALYSIS OF SLOPES BASED ON THE CONCEPT OF THE PERFORMANCE BASED DESIGN

Abstract

This paper presents the new methodology associated with the stability analysis of slopes. As for current design methods, the basic concept to determine the required factor of safety is vague. Essentially, the required safety margin to slopes should vary in accordance with the utility of each slope from socio-economical viewpoints. Therefore, this study applies the concept of performance based design to take into account the utility of slopes. The conclusions make it obvious that the methodology proposed in this study is very useful in the design of slopes.
