| Abstract | This study presents the behavior of sand containing fines under
cyclic loading. A series of the cyclic triaxial tests were performed
under uniform and irregular loading conditions. The test samples were
artificially made of Nakorn Pathom sand mixed with bentonite and kaolinite
in different percentages.
The
initial
sand. At
test results under uniform loading condition, showed
liquefaction strength for sand containing fines than
earlier cycles, less than about about 10 to 15, both
a higher
the clean
types of
fine content samples showed similar nature of decrease in liquefaction
strength defined by D.A. axial strain with an increase in fine content. At
more than 25 to 30 cycles, the samples showed an increase in liquefaction
strength with an increase in fine content. Clear relation between
plasticity index and liquefaction could not be found in this study.
Increase in liquefaction strength defined by D. A. axial strains after 25
to 30 cycles Has found with an increase in clay content.
A few irregular loading tests were also carried out by using
acceleration record of KAIHOKU-LG during 1978 MIYAGIKEN- OKI earthquake to
compare the behavior obtained under two different types of loading. Clear
effect of fine content on liquefaction characteristics under irregular
loading condition Ras not obtained. However, t he coefficient of
irregularity Has found to be 0. 584. |
