| Summary: | 碩士 === 中原大學 === 土木工程研究所 === 96 === Geosynthetic Clay Liners (GCLs) usually apply to the project
is utilize it absorb water of expand ability,to reduce the liquid
ooze,today global water resource is serious insufficient,child care
and effectively utilize water resource is very urgency.In water
resource stored and the pollution defended of underground
water,adopt adaptable blocking water material directly influence
fruitage of the Hydraulic Barrier.And now it used in Landfill、
reservoir、artifact water hole and other project of hydraulic barrier.
As a result of the GCLs apply used in tap water is fruitage and
used it for many years.Now many project is advance along the
coast,but the seaweater is include complex cation,and high cvalue
ation replace the sodium ation will influence it engineering
quality.So in this study will permeate with water and osmosis with
seawater,observe it absorb water of expand ability 、mineral
structure characteristic、Hydraulic Barrier fruitage of GCLs and to
discuss the variation of cation capacity.
According to this research，GCLs have very well hydraulic
barrier ability with the water environment,but with seaweater the
Moisture content and expand of GCLs will be decrease and to lose
hydraulic barrier obviously.As the result of X-rays diffraction
analysis the distance mineral lattice.The high cvalue ation replace
to cause the distance mineral lattice increase,and by Atomic Geosynthetic Clay Liners (GCLs) usually apply to the project
