“…The coefficient of secondary compression (Cα) value from conventional oedometer test for fibric was 0.0374 to 0.0901, hemic was 0.0225 to 0.0881 and sapric was 0.014 to 0.0851. According to Mesri [6] , soil with Cα values of more than 0.064 is classified as soil with extremely high secondary compressibility. The coefficient of secondary compression C α (=∆e/∆log t) was determined from the slope of the e-log t curves during the period of 4 to 24 hours after load increment, assuming that the secondary compression would have started 4 hours after loading.…”

This paper presents the engineering properties and compressibility behavior of various types of tropical peat soil collected from several locations in Malaysia. These soils represented fibric, hemic and sapric type of tropical peat with organic content ranging from 70% to 90%. The correlations of the various basic engineering properties of the tropical peat soils have been found to be close and new equations have been established. Loss on ignition (Organic Content) appears to be a very useful parameter for the peat. It correlates well with the natural water content, liquid limit, density and specific gravity. Compressibility behavior of various type of peat soil was measured using Rowe Cell consolidation test for accuracy and conventional oedometer test for comparison purpose. Compressibility index Cc and Cα was identified as two crucial parameters to estimate settlements in peat soil. Parametric study has been carried out at the end of the study to foresee the effect of surcharge on fibric, hemic and sapric peat ground. Based on the results obtained, it shows that fibric peat recorded the highest settlement followed by hemic and sapric peat with increase in consolidation pressure.

“…Cα is however directly related to changes in linear strain. Please note that this definition of the Cα complies with common practice, but differs from the original definition by Mesri [11].The shared isotache formulation implies that all inelastic compression results from visco-plastic creep. The NEN-Bjerrum model, therefore, assumes that creep rate will reduce with increasing overconsolidation and that overconsolidation will grow by unloading and by ageing.…”

Abstract. Construction of the 276 and 312 ha reclamation on the Holocene marine clay deposit in Jakarta Bay is on-going. Settlement has been measured during the construction in order to satisfy the requirement of residual settlement. This paper briefly discusses limitation of accuracy of settlement prediction based on purely parameters derived from laboratory and in situ testing, in particular the Holocene marine clay. A reliable 'observational' method which makes full use of the monitoring data is described and estimates reliable residual settlement. More accurate settlement method is then also briefly described taken into account complex loading history. Finally, the factors, which are source of inaccurate settlement predictions and its implications, are included in the discussion.

Abstract.A laboratory experimental research in creep behavior of soft clay marine sediments was done to investigate creep strain under reloading. A total of 52 oedometer tests were carried out with 16 slurry sediment samples subjected to cycles of unloading at preload removal pressure and reloading to higher design pressures. Common practice as well as more recent advanced methods of creep deformation analysis were used to refine the predictions. The study indicates that although preloading substantially reduces post construction creep, the analysis is very sensitive to creep indices at slight overconsolidation and the resulting creep may not be negligible at previously established limits of primary to secondary compression ratios.
