Özet
Many studies were performed to investigate the effect of the thickness of clay layer on the secondary compression. To find the stress-strain behavior of a tall specimen in the laboratory we have to face the major problem of friction. Without knowing the friction, the data obtained from the high specimen is not easy to interpret. The goal of the present paper is to explain the adoption of a new oedometer cell to measure frictional effects between the consolidation ring and specimen. It is observed that the side friction does not remain constant during the test and slightly increased with time at a decreasing rate. The amount of the side friction depends upon the level of the applied vertical consolidation stress on the specimen. Friction is found to be most significant at low stresses where the clay is still overconsolidated.
