Consolidation Characteristics of Lowly Organic Soil under Repeated Loading

반복압밀하중을 받는 저유기질토의 압밀특성

  • Published : 1999.04.01

Abstract

When the repeated loading, such as vehicel etc, acts on soft ground, consolidation behaviors due to repeated loading wil show different from standard one. A series of tests was performed to investigate the characteristics of consolidation of lowly organic soil subjected to repeated loadings. Lowly organic soil with Lig. 23.5% was sampeld in Chonbuk Province and tested using a partially and a fully repeated loadings. From test results it was found that void ration, volume change, consolidation coefficient, permeability and secondary consolidation coefficient were greatly affected according to the repetition number and the load weight. The secondary consolidation coefficient was decreased with increase of the repetition number. The results obtained from this research can be used as basic for the improvement of soft ground.
