Experimental and numerical investigation of slope stabilization by stone columns

摘要: In this study, an investigation has been performed on a small-scaled laboratory model and its numerical by the code of PLAXIS to see effect stone columns (SCs) placed vertically in soft soil slope terms stability, bearing capacity, settlements. Also, several hypothetical cases have examined code. Effect s/D ratios (distance between vertical axes SCs/diameter SCs) was also investigated ultimate settlement footing rested top model. Firstly, capacity properties were determined for unreinforced that is no SCs considered. Then, some values after installation with various s/D. The 2, 3, 3.5, 4. tests carried out simulated numerically analyzed two dimensions under plain-strain conditions Mohr–Coulomb analyses, computer code, which based finite elements method, employed. parametric stability slope. investigation, one layer layers presence water reservoir side slopes examined. analyses angles β, c/(γH), From test results model, obtained from it observed constructed increased; settlements decreased improvement SCs. performed, found increased 1.18- 1.62-fold as relative different parameters.
