Abstract

Cellular Foundation Mattress made of new materials such as high density polyethylene, are not currently use for the foundation of small and medium-sized buildings in Korea. Therefore, they need to be developed and verified based on domestic ground and field conditions. This study presents the basic design and construction method of Cellular Foundation Mattress. Since the foundation reinforcement effect of Cellular Foundation Mattress should be evaluated and verified for soft ground, a performance comparison evaluation was conducted using the Soilbag method, which is commonly used for the foundation of small and medium-sized buildings in Korea. After the mattress reinforcement, the settlement amount decreased by 38.4% compared to the original ground and the bearing capacity increased by 159%, confirming the same ground reinforcement effect and ground stability as the Soilbag method.

국내 중소규모 건축구조물 기초에 적용 사례가 없는 고밀도 폴리에틸렌 신소재 재료로 구성된 셀룰러 기초 매트리스가 건축구조물 기초 공법의 대안으로 정착되기 위해서는 국내 지반 및 현장 조건에 맞게 개량된 공법 개발 및 검증이 필요하다. 본 연구를 통해서 셀룰러 기초 매트리스의 기초적인 설계 및 시공 방법을 제시하였다. 셀룰러 기초 매트리스의 기초보강효과는 연약지반 대상으로 안정성 평가와 검증이 되어야 하기에 국내 중소규모 건축구조물 기초에 적용 실적이 풍부한 소일백공법과 성능 비교 평가를 수행하였다. 매트리스 보강 후 평판재하시험 결과, 원지반과 비교하여 침하량은 38.4% 감소, 지지력은 159% 증가하였으며, 소일백공법과는 동일한 지반보강효과 및 지반안정성을 확인하였다.
