Abstract

In this study, a complex behavior connector is proposed to overcome the problems that may occur when small pile pipe and micro pile is used as a friction pile concept in the lower foundation of an oil sand plant where a piloti foundation is used. The individual settlement and heaving of piles were connected in one group to allow the composite behavior. This study performed to analyze the load carrying capacity to identify a complex behavior. In addition, the shape of the composite behavior connector was examined to apply the advantages of pile-group and piled raft foundations to oil sand plants. A scale model was constructed to measure the behavior of the load. The stability and weakness of the device were selected to determine the shape of the connector using the scale model testing.

본 논문에서는 고상식(Piloti) 기초가 사용되는 오일샌드 플랜트의 하부기초에 소형강관 말뚝이나 마이크로 파일 등을 마찰 말뚝개념으로 사용할 경우 발생할 수 있는 문제점을 극복하고자 복합거동 연결체를 제안하였다. 말뚝의 개별 침하나 융기(Heaving)를 1개의 군으로 연결하여 복합거동이 가능하도록 하였으며, 하중 지지특성을 분석하였다. 기존 무리말뚝과 말뚝전면(Piled raft) 기초의 장점을 오일샌드 플랜트에 적용 할 수 있도록 복합거동 연결체의 형상을 결정하였다. 또한, 축소모형을 제작하여 하중에 대한 거동을 계측하고, 이를 통해 장치의 안정성 및 취약부위를 검토하여 연결체의 형태를 평가하였다.
