Numerical Study of Laterally Loaded Piles in Soft Clay Overlying Dense Sand

This paper presents the results of three dimensional finite element analysis laterally loaded pile groups configuration 1×1, 2×1 and 3×1, embedded in two-layered soil consisting soft clay at liquid limit overlying dense sand using Plaxis 3D. Effects variation length (L) layer thickness (h) on lateral capacity bending moment profile foundations were evaluated by employing different values to diameter ratio (L/D) (h/L) analysis. Obtained indicated that reduces non-linearly with increase thickness. Larger decrease was observed group piles. A non-dimensional parameter Fx defined compare layered sand, for which a generalized expression derived terms h/L number piles group. Group effect resistance maximum become insignificant exceeding 40% length. For fixed value thickness, single increased significantly only up an optimum embedment depth found be equal times 0.21 L/D 15. Scale has also been studied discussed.
