깊이 별 초기유효응력 차이를 고려한 1차원 압밀침하량 산정공식 = Consolidation Settlement in One-Dimensional Condition Considering the Variation of Initial Effective Stresses with Depth

국문 초록 (Abstract)

본 연구에서는 정규압밀 및 과압밀 지반에 대하여 깊이에 따른 초기유효응력 변화를 고려한 압밀침하량 산정식을 새롭게 제안하였다. 제안된 해석이론을 다양한 측면에서 검토하고 기존의 점성토층 중앙부의 초기유효응력을 이용한 압밀침하량 산정방법과 비교, 분석하였다. 분석결과 기존의 침하량 산정방법은 층을 나누는 개수에 따라서 침하량이 다르게 산정되며 정해에 비하여 45~100% 정도로 침하량을 과소평가하는 것으로 나타나 제안된 방법이 기존의 산정방법에 비하여 경제적이며 합리적인 방법이라는 결론을 얻었다.

다국어 초록 (Multilingual Abstract)

A series of analytical formula to compute settlements accounting for possible variations of initial effective stresses were derived. The comparison of computed values from conventional and newly-derived equations shows that computed settlements via the conventional equation unrealistically vary with the chosen number of layers in a clay stratum and also are 45~100% less than the value obtained from the newly-derived equation with exact mathematical integration.
