Analysis of the influence of pile cap thickness to deflection due to lateral load in sand

Analysis of the pile groups in noncohesive soil consisting of dense sand with varying pile cap thickness is presented small scale model through the experimental study in the laboratory of soil mechanics and geology. Pile groups (PG) of 2x2, 3x3, 4x4, and 5x5, of pile arrangement with spacing 3D and pile cap thickness (PC) 2D, 3D, 4D and 5D where D is the diameter of pile. This study shows the significant effect of various parameters of pile groups to lateral load and lateral displacement. The more piles in total number of pile groups, the smaller deflection of pile occurred in the same PC. The thicker of Pile cap, the smaller deflection of pile occurred in the same PG. PC thickness of 5D will give the smallest deflection if compared 2D, 3D and 4D in PG of 2x2, 3x3, 4x4 and 5x5.
