Abstract

보통으로 다져진 실트질 모래(Dr=50%)에 대한 액상화 전후 상태에서의 반복하중에 의한 동적거동을 연구하기 위하여 몇가지의 압밀응력비로서 압밀시킨공시체에 대해서 일련의 일련의 반복삼축시험을 수행하였다. 연구결과로서 압밀응력비가 액상화거동에 미치는 영향을 나타내었으며 또한 액상화 전후의 동적거동을 비교하였다. 그리고 액상화 후의 거동은 선행액상화시의 응력반전여부에 의해서 절대적으로 좌우된다는 사실을 보여주고 있다. 결론적으로 액상화를 경험한 공시체의 액상화저항은 액상화를 경험하지 않은 공시체에 비해서 이방압밀의 경우에는 높고 등방압밀의 경우에는 낮다.
