| To increase the bearing capacity of existing auger-drilled piles and decrease the noise and vibration during the installation of the piles, Spirally-reamed and Under-reamed auger trilled piling methods were developed. Field tests were performed to verify the inurement degree of bearing capacity and the constructional possibility of the new augerdrilled piling methods. The test results showed that the bearing capacity of the new augertrilled piles was fairly improved by the grooves of piles, and the skin friction was affected by the groove height and spacing between grooves. It was found that the skin friction takes the great part of total bearing capacity in auger drilled Biles, i.e. 74~80% in case of the existing methods and 81~86% in case of these methods. Moreover, the settlement of spirally-reamed and under reamed piles was smaller than that of the existing augerdrilled pile for the same loading state. |
