- Abstract
- Pressure penetrating pipe (PPP) piles which use hydraulic jacks make it possible to check the correct pile bearing capacity and are also effective in narrow areas. In this study, pile load tests were performed to estimate the allowable bearing capacity of the PPP piles, which were installed in weathered soil overlying thick weathered rocks.
Using the measured data, the shaft and base resistances were determined. From the comparison of the allowable bearing capacity values between domestic specifications and those obtained from pile load tests, the domestic specifications underestimated the bearing capacity of PPP piles. Therefore, a proper method was proposed for the evaluation of the bearing capacity of PPP piles.
