ULTIMATE SOIL PRESSURES FOR PILES SUBJECTED TO LATERAL SOIL MOVEMENTS

In this research, a series of lab model tests was conducted to investigate the behavior of coupled piles subjected to lateral soil movements, and to determine the ultimate soil pressure on the pile shaft. Two piles in a row and in a line were considered. The ultimate soil pressures along the pile shaft for 2 piles in a row and in a line with pile spacings of 3 and 5 times the pile width (B=20mm) were lower than those for single passive piles. Group effects still existed even with a pile spacing of 5 B for coupled piles in a row and in a line. Group factors decrease as pile spacing decreases for piles in a row. Test results also show that different distributions of limiting soil pressures along the pile shaft were developed for single and coupled passive piles.
