Abstract

인천국제 공항에 분포하는 해성세립토 지반에서 일련의 CPTU와 DMT를 실시하고 그결과로부터 구한 비배수전단강도($s_{u}$ ), 과입밀도(OCR), 압밀계수($c_{h}$) 등과 같은 지반 정수와 기존의 시험자료 등을 분석하여 두 시험 결과를 비교하였다. 이 분석에의하면, CPTU와 DMT 두시험은 모두 피에조콘 정수, $B_{q}$ )로 분류하여 점성토인 지반에서 보다 신뢰성이 높은결과를 주었으며, 또한 해석방법에 따라 지반정수 산정결과에 큰 편차를 보여, 적절한 해석방법의 선택이 신뢰성있는 지반정수의 산정을 위한 주요한 인자임을 알았다. 그리고, 소성적 성질이 낮은 세립토 지반에서의 CPTU와 DMT를 이용한 비배수전단 강도 또한 과압밀비의 산정은 상당한 오차를 유발할 수 있다고 판단되었다.
