Cα/Cc Concept Applied to Compression of Peat

摘要: Eight long-term multiple-stage-loading oedometer tests were performed on a fibrous peat from Middleton, Wisconsin. Both conventional-size and large specimens treated with pore-pressure measurement. Load-increment duration load-increment ratio additional variables of the testing program. Time-settlement curves show that coefficient secondary compression (Cα) is not constant but increases in time under effective stress. Plots Cα versus index (Cc) indicate that, for this peat, poor linear relationship exists between Cc, worsens if tertiary points are included. Cα/Cc void significant scatter general, decreasing ratio. sample disturbance factors affecting Cc relationship. The fact inorganic soils do exhibit exaggerated creep effects or may explain, part,...
