In this research work, a 3D numerical modeling technique is proposed based on the 3D particle flow code in order to investigate the failure mechanism of rock foundations. Two series of footings with different geometries and areas are considered in this work. The failure mechanism obtained is similar to that of the Terzaghi’s but there is a negligible difference in between. Lastly, one equation ...

This study aims to demonstrate the effects of geogrid reinforcement on bearing capacity strip footing under eccentric loading. Numerical analysis using finite element program called (PLAXIS 2D Professional v.8.2) are presented. The effect each depth ratio topmost layer (u/B), vertical distance between consecutive layers (h/B), number (N), and effective (d/B) were studied, where (B) is width. Al...

this research examines the behavior of soil-reinforced piles and applied loads based on the analytical method and by using the numerical results of flac3d software for comparison with the analytical results. the analysis was based on a method called virtual retaining wall, the following into consideration: an imaginary retaining wall that passes the footing edge the bearing capacity of footing ...

following the recent work of the authors in development and numerical verification of a new kinematic approach of the limit analysis for surface footings on non-associative materials, a practical procedure is proposed to utilize the theory. it is known that both the peak friction angle and dilation angle depend on the sand density as well as the stress level, which was not the concern of the fo...
