Soil names was determined by site boring record of the boreholes. Soil layers were

determined based on classification in situ, state and distribution of them.

Site investigations were include drilling, taking sample:

Drilling and taking samples at 2 Borehole;

42 taken samples in situ and 10 taken samples were tested in laboratory;
