연약지반의 다차원 압밀해석을 유한요소법으로 해석하기 위하여 점토의 구성방정식으로서 신생퇴적 점토층에서 압밀시에 예상되는 creep와 같은 변형의 시간의존성거동을 표친하는 탄 점소성 구성방정식을 새로히 제안하기 위하여 한계상태 개념으로부터 개발된 수정 cam clay 모델을 보완하여 음력변형해석을 통하여 실측치와 비교한 것이다. 그 결과 대체적으로 실측치와 접근하고 있음을 알 수 있었다.
This study was performed to investigate the effect of time-dependent creep on the deformation analysis of multi-dimensional consolidation using the finite element method for young Sedimentary clay. It was assumed that the creep in the clay had occured during consolidation. In the analysis, the Modified cam-clay theory originated from the critical state theory was used as the constitutive equation, in which a term equivalent to the creep was supplemnted. The results of the analysis were in good agreement with the observed values in the field.
