PENGUJIAN OEDOMETER PADA TANAH RESIDUAL VULKANIK TROPIS

Hadi U. Moeno

Abstract


Test of Oedometer or One Dimensional Consolidation usualy done to get deformation parameter suchas compression index Cc, coefficient of consolidation cv and pre-consolidation pressure pc, usualydone to the sedimentary soils. This research done to the tropical residual soils which condition ofphysical of in field is not saturated then is done testing of oedometer at condition of saturatedspecimen and not saturated. From result obtained simple visible that there is the relation of strongcorrelation between values Cc for Sr = 1 and Cc for Sr < 1, with equation of continuity of empiricalcorrelation is CcSr=1 = 1,33 (CcSr<1), and so it is with parameter OCR that is OCR for Sr = 1 equal toOCR for Sr < 1.

Keywords: Oedometer, Cc, OCR.
