This study was intended to investigate the consolidation characteristics of lowly organic soils and highly organic ones, with organic content 15 of and 68 % respectively. which were sampled from three different soil regions in Chonbuk province. The results were obtained partly from standard consolidation test but mostly from single increment consolidation test in which each sample was held under the first sustained load for weeks. Highly organic soils retained considerably larger void ratio than lowly organic ones. Decrease of void ratio due to load increment was gradual in lowly organic soils and abrupt in highly organic ones. The long-term compression quantity of the highly organic soils became linearly proportional to the logarithm of time after 5 minutes. The lowly organic soils showed a compression pattern similar to that of clay. For highly organic soils, the secondary consolidation coefficient appeared to have a constant relationship with the logarithm of consolidation time, and therefore may be used as a significant factor in estimating the long-term settlement.
