수평저항력 보강 Pile의 말뚝지지력 특성

Abstract

Although there have been many studies on pile foundations subjected to vertical load domestically and externally, the domestic studies on pile under horizontal load have been limited. The purpose of this study is to develop a pile, which allows the pile member and column member to overlap with each other, and the lateral load to be supported not only by a pillar member but also by pile member in order to address the problems above. The results of field load test showed that the horizontal resistance of pile is higher by 4-4.5 times compared to general ones. It was found that the improved horizontal resistance corresponds to the wing area of the upper fixed pile, suggesting that the resistance is proportional to the wing area. The 1/β depth should be considered for the reinforcement against horizontal force to a proper depth.
