Evaluation of Initial Specimen Condition and Its Effect on Consolidation Properties of Saturated Clay

摘要

The reliability of results of laboratory tests on soils depends on the specimen quality of the initial specimen condition. The quality of specimens prepared using different methods, from Clay samples extracted using different techniques and subjected to Different periods of storage, can be evaluated based on the mea- Surement of residual porewater pressure. For a laboratory-fabri- Cated normally consolidated clay, the residual porewater pressure Decreases when using an inferior sampling technique or preparation Method and when the storage time increases, with the effect from The method of specimen reparation dominating.
