A Study on Slope Stability Analysis That Considers Ground and The Slope Counter Measure Interactions
Satoru OHTSUKA
Countermeasure for slope has been designed by the limit equilibrium method. It is simple and useful, but it can not consider the detailed failure mechanism and soil-countermeasure interaction accurately. It has been made clear that the rigid plastic finite element method (RPFEM) can estimate practical slope stability in the previous study. The applicability was examined through some case studies quantitatively from the view point of the relationship between interaction and failure mode.
In this study, joint element was installed in countermeasure and slope contact side. As a result, countermeasure influence is not considered in excess. The insertion of countermeasure direction of the depth was considered. As a result, it becomes near the achievement elephant. And, the slope interrelation is appropriately expressible with the countermeasure. Nailing was used as an anchor to examine the applicability of this technique. In this study was examined through some case studies quantitatively from the view point of the relationship between interaction and failure mode.
