- Abstract
- In this research, the characteristics of settlement and consolidation behavior of the composite ground formation reinforced by Recycled-Aggregate Porous Concrete Pile(RAPP) were evaluated by conducting a series of laboratory chamber tests. The effect of settlement reduction was verified by comparing the settlement of the composite ground formation with that of the unreinforced ground. In addition, it was studied how much the RAPP can accelerate consolidation in assessment of the degree of consolidation in the composite ground formation. The amount of settlement reduction was decreased with an increase on surcharge pressure, but it was greater than that of the SCP method. The RAPP and the SCP showed a similar rate of consolidation.
