Abstract

ÖZET
Son yıllarda dünyada ve ülkemizde toprakların kimyasal ve mekanik stablizasyonu ile elde edilen karışımların yeni bir yapı malzemesi olarak kullanılması çalışmalarına oldukça
önem verilmektedir. Bu araştırma topraklara katılan bazı stabilizan madlerinin toprakların fiziksel, kimyasal ve su geçirme özelliklerine etkisi ile bu maddelerden elde edilen karışım
ların sızma kayıplarım azaltmak için tarla içi sulama kanallarmıda ekonomik kaplama malzemesi olarak kullanılabilirliğini saptamak amaciyle yapılmıştır.

A RESEARCH ON THE UTILIZATION OF SOME SOIL STABILIZERS FOR LINING THE FARM IRRIGATION DITCHES

Conservation of the irrigation water
is one of the important problems in
agriculturally developing countries. Lining
the irrigation canals, decreases
seepage losses and increases covayaııce
efficiency; hence it advances economical
use of irrigation water.
Taking into the cosideration above
mentioned ideas this study is conducted
to determine an economical lining
matt.rial which is suitable to regional
conditions and easily obtinable from
the vicinity to prevent seepage losses
in the irrigation projects. For this
purpose 6 soHs having different texture
and Atterberg timits;ıs a base material
among" the 17 soil samples taken from
the diffierent parts of the Atatürk
Üniversitesi Ziraat Fakültes: Experiment
Farm. Variying methods were
employed to determine mechanical,
physical and chemical properties of
these six soils. Cement, lime, bituminous
(emilkote) emulsion asphalt
and used engine oil were used as
soil additives to stabilize the soiI.
These additives were mixed in different
ration and five samples were taken
for each mixture.
Soil miıı;tures prepared with different
additives mentioned abov~ are
tested for compression and durability
and freezing -thawing in the laboFatory.
Additionally these materials are tested
in the field using model canals for
seepage losses. Following conclusion
. is drawn by using the data obtained
from the tests mentioned above.
- Most of the soils used in this
study have common gradation accorcting
sieve analysis.
- Atterberg Limits for the soHs
tested which are used as criteria
in engineering soit classification differ
according to amount of clay and
silt present in the soiI. Liquid limit
values are between 24,7 % and 31,3
plastic index vaIues are between 4
% and 15 %. These figures give information
about the water content of
the soils at their liquid limits.
--:- The soil used a material
ın this study classified according to
A. A. S. H. O dasification syste~.
SoiI number 1 is A-I-a (O), number
2 is A-2-4 (O), number 3 is A-6(2)
number 4 is A-2-6(0), number 5 is
A-6(6) and muber 6 is A-4 (I).
- The prepared mixtures tested for
freezing thawing, wetting-drying in the
laboratory. The material is going to to
be used as a lining material for the canals
in the field is determined according to
the results obtained from the tests
mentioned above. Freezing-thawing tests
were in twelve period. The minimum
10st in fereezing-thawing test were
observed at number 2 plastic cement
mixture (3 % ) and maximum loost
at number 17 soil-cemet-lime mixture
(29 X).
The minimum lost in wetting-drawing
tests were observed at number 2
soileement mixture and maximum lost
at number 8 soil-bituminous mixture
(51 %).
Plastic soil-cement mixture which
is prepared with the soil number 2
