Abstract
Authors proposed a sheet-pile foundation that combined sheet piles with footing. Sheet-pile foundation can be expected the reinforcement effect of constraint of the ground. Because sheet piles reinforce the inside ground of sheet piles, the sheet-pile foundation has higher seismic resistance than footing foundation.
In this research, a series of lateral static loading tests of sheet-pile foundation and footing foundation were conducted. The pressures of the bottom of the footing were measured, and the ground displacement was calculated by image processing system. It was found from these results that sheet-pile foundation had the improved effect of seismic resistance and settlement, and that the improved effect was demonstrated by vertical resistance of sheet piles.
