Impact of Suction on the Near Surface Lateral Soil Response using Centrifuge Modeling

Recent studies have shown that unsaturated soils lead to greater lateral pile capacity. This study aims experimentally assess how suction stress affects the response of piles in cohesionless soil. Two centrifuge tests were performed at 50 g evaluate effect Lateral loads applied monotonically on a single free-head displacement-controlledmanner maximum head displacement 0.44 m. The first test was conducted fully saturated soil, while second an state with mixed unsaturatedsaturated soil layer. water table lowered about 0.12 times embedded depth ensure condition zone closer surface assessment indicates influenced response, leading larger for similar displacements comparison test. Experimental findings reveal played meaningful role magnitudes bending moments and resistances soils.
