초록
In this study the behavior of piles with an extended head is invested experimentally using reduced-scale model tests. Special attention is given to verifying the increase of end bearing capacity of piles with spreading head. Model piles and extended head plates made of steel pipe were used in this study. Bearing capacity of piles is regarded as only end bearing capacity. The study analyzed the tendency of single and group pile of bearing capacity compared with the existing PHC pile, and examined optimum effect of extended head.
