모래다짐말뚝(SCP) 지반개량을 위한 굴패각-모래 혼합토 실험연구

초록

In order to investigate a recycling possibility as a construction material of oyster-shells, the geotechnical characteristics including N-value, confined compression and shear strength for oystershell mixed soils were quantitatively examined. Experimental results show that the oyster shell mixed soils are lighter than sand in weight, and have similar characteristics of shear strength with sandy soils. Based on theexperimental results it is highly judged that the crushed oyster-shell can be a substitute of sand as the SCP method.
