본 논문은 모래지반에 박힌, 기하학적 특성과 설치방법이 서로 다른 모형말뚝의 극한상장지지력에 대한 연구이다. 기하학적 특성의 측면으로는 균일직편말뚝, 선단확대말뚝, 다층확대말뚝과 앵커플레이트가 시험되고 기일직경말뚝에 대한 말뚝설치방법이 극한지지력에 미치는 영향을 조사하기 위해 매설, ao입, 진동관입방법이 연구되었다. 실험결과에 의하면 기초가 상장력과 압축력을 받는 경우에는 선단확대 말뚝이, 오직 상장력에 대해서는 앵커플레이트가 가장 효과적이며, 또한 말뚝설치방법 및 타입 말뚝의 선단 모양은 상장지지목에 큰 영향을 준다는 것이 밝혀졌다.

This paper performs a study on the influences of shape and installation method on the ultimate uplift capacity of model piles in sand. Several model piles of different shape, such as straight sided, single-underreamed, multi-underreamed and anchor plate are used. The effects of installation method are studied with buried, driven and vibrotriven piles. Based on model test results, it has been found that when the foundation is subjected to atrial up- lift and compressive load as well, a single-underreamed pile is most effective. When the loading is axial uplipt only, it is likely that anchor plate would be most efficient. Installation method and tip configuration of pile have significant influnce on uplift resistance.
