CHAPTER HIGHLIGHTS

Causes of slope failures – Short- and long-term failures – Types of land slides and slope movements – Factor of safety – Infinite and finite slopes – Analysis of infinite slopes – Analysis of finite slopes: planar and circular failure surfaces: ϕu = 0 analysis, friction circle method, Fellenius method of slices, Bishop's simplified method – Taylor's stability chart – Location of critical circle

13.1 INTRODUCTION

Landslides are the downward and outward movements of slope materials because of exhaustion of required shear strength. The slope materials may be composed of natural rock and soil, artificial fills, or combinations thereof. Potential landslides in natural slopes may be identified either by ...
