A STUDY FOR CHARACTERISTIC OF VERTICAL BEARING CAPACITY OF FOOTING FOUNDATION WITH SHEET PILES BY STATIC LOADING TEST

Abstract

Authors proposed the sheet-pile foundation that combined sheet piles with footing. Sheet-pile foundation can expect the reinforcement effect of constraint of the ground. Because sheet piles reinforce the inside ground of sheet piles, the sheet-pile foundation has higher bearing capacity than footing foundation.
In this research, the series of vertical 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 bearing capacity of bottom ground and friction of sheet piles.
