Abstract

Slope stability analysis is one of the most important steps in slope related projects. Among variety of two and three-dimensional slope stability analyses, limit equilibrium methods are more interesting for geotechnical engineering. An important element which affects factor of safety in these methods is how to calculate interslice forces, for two-dimensional and intercolumn forces, for three-dimensional analyses. The purpose of this study is to evaluate the importance of intercolumn forces in three-dimensional slope stability analysis based on the comparison between two-dimensional and three-dimensional stability analyses. Also, this paper proposes a new method to calculate the intercolumn forces with more details and fewer assumptions compare with previous methods. Three-dimensional slip surface and irregular slope geometry could be considered by this new method. An optimization based three-dimensional limit equilibrium computer code is under developed by authors to reach the factor of safety by using this new method.
