Abstract

The investigation of the undrained strength and the important several undrained geotechnical properties was, in detail, made for highly plastic soils using the field and laboratory testing results. The plastic index, activity, water content, and effective unit weight did not show the notable relationship with both Su and normalized Su. The OCR, sensitivity, and undrained elastic modulus presented remarkable tendency with normalized Su. It could be concluded that the use of the normalized Su may lead to the reasonable results then the normalized Su needs further research.

본 연구에서는 고소성토 비배수강도와 주요 특성치들의 관계에 대하여 다양한 현장 및 실내시험 결과를 활용하여 심층적으로 고찰하였다. 소성지수, 활성도, 함수비 및 유효단위중량 등은 비배수강도 및 정규화 비배수강도 경우 모두 예상과 달리 특별한 관계를 보이지 않았다. 과압밀비, 예민비 및 비배수탄성계수 등은 정규화 비배수강도와 분명한 관계를 보여주었다. 정규화 비배수강도 방법이 비배수강도와 특성치들의 연구에 크게 도움이 될 것으로 기대된다.
