The Grain Size Distribution of Sandy Soils in Libya
Where that all types of soil consists of grains in different sizes, and these grains can be obtained and identified by
knowing the results of grain size distribution of the soil tests. The results of grain composition of the soil are the basis for the
classification and be very useful in obtaining some characteristics of the soil. So the main aim of the present study is to
investigate and classify the particle size distribution of sandy soils in Libya. More than fifty soil samples collected from
many regions, North, West and South of Libya. Laboratory sieve analysis tests performed on disturbed soil samples. As well
as to provide an indicator of general engineering behaviour and good understanding, test results are presented and analysed,
some of the significant parameters such as the gradation parameters and grain diameters for these types of soil have been
identified, also found links between some of these parameters. Soil classification based on particle size analysis(USCS) is
used. In addition, conclusions, recommendations are made.
Key words- Grain size distribution of soils, Sieve analysis tests, Soil classification.
