The study determines the optimum location of the pile and its optimum inclination to achieve the maximum stability. The results show that using the 3D aspect gives more insight into the complicated slope stability problem. The findings of the research were compared to other findings from the literature. A parametric study was undertaken to study the effect of pile position, pile inclination, pile length and pile diameter on the factor of safety of the piled-slopes. The 3D model was verified using experimental data from the literature for a stabilized silty sand slope in a large-scale physical model.

This allows seasonal variations of river water levels behind embankments and their effect on the overall slope stability to be modeled. We use cookies to provide you with the best possible user experience. A 3D finite element model was developed using the finite element program PLAXIS. PLAXIS 2D CE V20.02.00 Release notes New features 2D Classic converter tool. A 3 dimensional (3D) finite element study is carried out to investigate the effect of different parameters on the stability of slopes stabilized with piles. Stabilized slopes with piles are numerically studied in the current paper. Soil Nail Walls details and Commercially available software PLAXIS 2D and GEO5 were. Piles are commonly used to stabilize slopes or to improve slope stability. Free read or download Geo5 Slope Stability Manual High School Slope. Slope stability can be achieved using different methods. Comparing the results, the limitation of 2D analysis for piled cohesive-frictional slope is highlighted. In 3D analyses, it is shown that spacing ratio beyond S/D = 4 ( S: pile spacing, D: diameter of the pile), the soil will flow between piles leading to a total vanish of the arching effect when S/D exceeds 12. Piles with free head contribute marginally to the increased factor of safety of cohesive-frictional slope. According to the obtained results, the fixed pile head located at the slope middle better improves the stability and reduces the optimal length of the pile. Next, more rigorous parametric studies taking account of the exact geometry was carried out using 3D analyses. First, 2D parametric studies were performed to identify both the optimal location and length of the pile as well as the effect of pile head conditions. in this project, two different software ( geo5 and plaxis 2d).
