| Abstract | One-dimensional compression tests were conducted on
the mudstone granular materials using the Rowe cell
consolidation apparatus. Th e test material was used as
rockfill at Chiew Larn dam in Surat Thani province ,
Thailand. Emphasis was placed to understand the stressstrain behavior of the granular mat erials with the
variations in gradation and water content. In analyzing the
effect of gradation, the experimental program included the
compression te sts on the samples from nine different
gradation curves and the parameters including uniformity
coefficient {Cu ) , maximum particle size and fine content
(- #200 mesh ) were based upon. The samples from each
gradation curves were tested in five different conditions:
{l ) air-dry, ( 2) wet{almost fully saturated), {3)moist{w=8%), '
(4) initially dry then wet{wetting on air-dry sample ) and
(5 ) initially moist then wet {wetting on moist sample ). The
compaction tests were also done on the representative
samples from all the gradation curves to obtain t h e maximum
dry density and optimum moisture content. It was clearly
observed that the compressibility increased with an increase
in uniformity coefficient {the sample becomes well-graded),
fine content and maximum particle size. Since the narrow
difference in maximum particle size {8mm, 4.76mm and 3.35mm)
high compressibility of the relatively well- graded
materials of this study was likely to be contributed by the
higher content of fines than the effect of grain-size
distribution of the coarse fraction. The additional
settlement due to wetting was distinct in the samples
compacted in dry condition and the axial strain increases by
1.68 to 4.76% from dry to dry the n wet condition. The
values of the additional axia l strain increase with an
increase in fine content of the samples. For the samples
prepared in moist condition{w = 8%) , the additional
settlement due to wetting was negligible. |
