Critical Assessment of Slope Stability Analysis

Failures of mass movements often result in extensive property damage and loss of human life. It is recognised that ensuring the stability of both natural and man-made slopes continues to be a fundamental issue in geotechnical engineering. There is no universally accepted method for the prevention or correction of landslides. The comparative performance of the various analyses has been carried out successfully using case studies. A visco-plastic flow model has been proposed to estimate lateral forces on piles used for slope stabilisation. Slope stabilisation due to the presence of a row of piles has been investigated using two distinct lateral load estimations. Eight well-known methods of slope stability analyses have been adopted and computer coded to re-calculate FOS values for a slope reinforced by a row of piles. The book is intended primarily for use in university courses, at both the undergraduate and graduate levels. The author also expects that the book will serve as valuable reference material for practising engineers.
