The California Bearing Ratio (CBR) has long been recognized as an important
parameter for determining the bearing capacity of earth structures. The aim of this
research is to develop the ...
Soil stabilization is given more emphasis in order to enhance the geotechnical characteristics of
expansive clay to meet technical requirements in the building sector. The additives selected for
this project are ...
The infrastructure is constructed in unsaturated soils. However, the principle of saturated soil
mechanics is adopted in the geotechnical design of structures. To follow a sustainable approach
and reduce costs, it is ...
Expansive soils have the inherent property of swelling when they are adsorbed water and
shrinking when they are dried. This property of expansive soil causes to damage
structures constructed on it. To minimize ...
The study of pile foundations in liquefiable soil subjected to dynamic loading is a very
complex and coupled process. A finite-difference-based computer program FLAC3D
is used to model the dynamic response single pile ...
The knowledge of temperature effect on index properties and thus the understanding of its
behavior is very essential for a complete understanding of the various cases of Geotechnical
Engineering problems and for conducting ...
The use of underground buried pipes is growing fast in transporting clean water, sewage,
telecom lines, gases and other chemicals. These buried pipe lines can affect the lives of
people directly. Therefore, studies ...
Self-supported, directly-embedded wood and concrete poles are widely used by the Utility Service
of Ethiopia to support low to high-voltage transmission lines. This study deals with examining the
effect of backfill ...
Local site conditions and foundation configurations have a great deal to do with
damages to structures built on the flexible ground during earthquakes. Hence, the
investigation on the energy transfer mechanism ...
Expansive soils swell and shrink due to changes in water content. This causes damage to structures
founded in expansive soils. One common stabilization method for the improvement of expansive
soil behavior involves the ...
Nowadays, the need for different kinds of naturally occurring construction materials is
increasing in the road construction industry. One of these materials is laterite but does not
usually meet the specification to ...
The volumetric change in fine-grained soil with changes in moisture content is one of the
most important phenomena. The soil shrinkage characteristic curve describes the
magnitude of the variation in bulk volume due ...
Soil is the ultimate foundation material which supports the structure. The proper functioning
of the structure, depend on the engineering properties of the underlying soil. Investigating
the engineering properties ...
The (GRS-IBS) Geosynthetic Reinforced Soil Integrated Bridge System is a composite
bridge structure built using closely spaced layer of geosynthetic reinforcement and
compacted granular backfill of GRS abutment that ...
A Simplified Model to Estimate Soil Water Characteristic Curve from Basic Soil
Properties for Shrink-Swell Soils, Case in Bahir Dar, Ethiopia.
Expansive soils or shrink-swell soils are soils that, because of their ...
Piled raft foundation is a geotechnical composite construction consisting of three elements: piles,
raft and soil. In piled raft foundation, the superstructure load is shared between the piles and the
raft. The analysis ...
Particle shape plays an important role in the engineering behavior of the soil in terms
of its permeability, packing density, dilatancy and shear strength. Dilatancy is the
ability of granular soil to change in volume ...
The construction industry in Ethiopia is the major sector where public and private stakeholders are investing a huge amount of fund and it has a fundamental role in the socio-economic development of the country. The Ethiopian ...
The change in river morphology in river systems is described by river bank erosion, river bed level change
and lateral channel change. The alluvial river channels in Lake Tana sub basin in the upper Blue Nile
basin have ...
