Behavior of piles in palm biodiesel contaminated mining sand

This paper presents a practical procedure for preliminary assessment of axially loaded piles embedded in palm biodiesel contaminated soils. The effects of several model parameters such as palm biodiesel contaminated soil, pile length, pile cross-section geometry and pile-soil nonlinearity on the axial responses of the soil-pile system are investigated. The parametric studies show that the palm biodiesel contamination of the surrounding soils and geometric properties of the pile greatly affect the responses of the pile.
