Experiments of soil compacting effects of GFRP pile in peaty soil


Abstract:
Three glass fiber reinforce polymer piles with diameters 38, 75 and 95 mm respectively were penetrated into peaty soil. The law of land upheaval with radial distance, the law of soil compacting pressure with depth and radial distance during pile-sinking, and the friction change along piles were monitored.The law of land upheaval with radial during pile-sinking, and the law of soil compacting pressure with depth and radial distance were analyzed. The experimental results show that the maximum land upheaval occurs at 1.50~2.50 times the pile diameter from the axis of pile when pile is penetrated into soil at a depth of 0.15 times the pile length. At the end of pile-sinking, radial soil compacting pressure increases along depth direction.
