초록

개별진공압밀공법을 적용한 연약점토 지반의 압밀거동을 분석하기 위하여 Plaxis 2D를 이용하여 유한요소해석을 수행하였다. 진공압을 묘사하기 위한 세부적인 방법을 unit-cell 해석 결과와 함께 제시하고, 실제 시공사례를 모델링하여 수치해석결과와 현장계측결과를 비교해봄으로써 개별진공압밀공법이 적용된 연약지반의 압밀거동을 예측하기 위한 Plaxis 2D의 사용 가능성 검토와 해석기법을 제시한다.

An individual vacuum consolidation system has gained a popularity for a ground improvement of soft clayey soil. Finite element anaylses have been performed to simulate the individual vacuum consolidation system using a Plaxis 2D. The modelling procedures of the vacuum consolidation system are presented with the results of an unit-cell analysis. In addition, a case study was carried out to assess the applicability of the Plaxis 2D for simulating the consolidation behavior of soft ground subjected to the individual vacuum pressure.
