This collection of 26 technical papers focuses on the state of the art in slope stability analysis, design, and practice. All of the papers seek to use modern analysis and instrumentation tools to better define the factors both causing and mitigating stability problems in slopes. The topics include: case histories of both natural and constructed slopes; slope stabilization methods; rock slope analysis; shear strength evaluation; centrifuge testing; limit analysis; 3-D analyses; finite element and finite difference methods; progressive failure analyses; and probabilistic methods using Bayesian and random field approaches.
