Experimental tests are very important to determine the engineering properties of soils in
geotechnical engineering. Special expertise and care are required to perform these tests.
The unconfined compression test is also one of them. Thus, there is a need to develop
models to quickly predict the unconfined compression strength of soils. The researchers
attempted to develop correlations to predict the unconfined compressive strength from
index properties of soils, which are easier and quicker to determine. This paper
describes the geotechnical properties of soils in Assiut Governorate, Egypt. Different
properties of soils were taken from numbers of geotechnical reports that were conducted
by the authors through the engineering consulting center, Faculty of Engineering, Assiut
University. All tests were performed according to Egyptian Code,2001. According to
USCS the soil samples were classified as CH, CL, MH, and ML. Finally, relationships
between unconfined compressive strength and index properties of soil were drawn. Best
possible prediction models were developed using a statistical approach. The developed
predicting formulas were compared with obtained values from tests. It was found that
there is very close between predicted values from prediction formulas and obtained
values from laboratory tests.
