Abstract

The behavior of rocket pile embedded in sand was investigated using 1-g physical modeling to explore the behavior of rocket pile carried to static/cyclic axial load. The effects of relative density of sand, pile slenderness ratio (L/D), fin-length ratio (Lf/L), fin-width ratio (b/D), fin position and surface roughness (Ra) of the modeled pile on the ultimate load capacity and settlement of rocket pile were investigated. The study showed that using fins progress the pile load capacity and reduce settlement values of rocket pile compared with plain pile. The experimental study showed that using using fins improve the pile load capacity and reduce settlement values of rocket pile compared with plain pile under quasi-static cyclic loading. The improvement in pile load capacity and a reduction of settlement directly proportional with the fins width ratio (b/D) and fins depth ratio (Lf/L). based on the results, a series of charts are presented to estimate the pile load ratio improvement and settlement reduction in terms of fins length ratio, fins width ratio and fin /pile roughness.
