Abstract
Adama is one of the most developing towns in Ethiopia as a conference and a tourist resort center. A lot of construction work is constructed at present. It is also expected that much more construction is going to be done in the future. However, very little work is done in investigating the engineering properties of soils of Adama town.
One of the most important engineering properties of soil is its shear strength or ability to resist sliding along internal surfaces within a soil mass. All stability analyses in the field of geotechnical engineering, whether they relate to foundation, slopes of cuts or earth dams, involve a basic knowledge of this engineering property of the soils.
In this research shear strength characteristics of Adama soil is studied. The shear strength parameters (c and ะค) are studied using disturbed soil samples remolded with different densities and water contents in order to simulate the field condition. The shear strength test is done using Digital Direct/Residual Shear apparatus.
The result obtained from the shear strength tests shows that as the density of the soil increase the shear strength of the soil also increase. The cohesion of the soil is strongly affected by the water content of the soil where as the angle of internal friction of the soil is not significantly affected.
