| Abstract | This thesis presents a study on the consolidation
characteristics of clay. Undisturbed samples of soft and medium
clays from Samut Prakarn area were tested in order to
investigate maximum past pressure, compressibility
characteristics and influence of load increment ratio and load
increment duration. Tests were carried out in lever-arm type
oedometer.
Ma xi mum past pressures were determined by standard loading
procedure i.e., doubling the load increment after every twenty
four hours duration. The soft and medium clays are found to be
normally consolidated clays having OCR values between 0. 73 and
0. 91.
The load increment ratio has been varied from a value of
0. 50 to 2. 0 and the load increment duration from 1 day to 7
days. It was found that the compressibility of both the soft
and medium clay is not significantly affected by the load
increment duration but is affected by load increment ratio.
Moreover, load increment ratio variation shows no effect on
coefficients of consolidation whereas coefficient of secondary
consolidation is influenced by load increment duration but
coefficient of primary consolidation remains un- affected. |
