In tropical countries, including Ethiopia Expansive soils are difficult deposits for civil
engineering construction because they swell and shrink during the wet and dry seasons,
respectively. The ...
Accurate and cost-effective approaches are required to determine the unsaturated soil
property functions. Past research studies have indicated that particle-size distribution
data of soils are a ...
In recent years reinforced soil retaining structures are both technically and economically various advantages over other retaining structures; especially when their will be property limitation and under poor soil conditions. ...
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 ...
The use of Roller Compacted Concrete Pavement (RCCP) is widely expanding throughout the world because of its benefits of reduced cement content, early opening to traffic, economic benefits and high speed of implementation ...
Many road networks were built by cutting slopes. Roads which pass on the hilly and
mountainous terrains of Ethiopia experienced excavations performed by blasting during
construction stage due to variable topographical, ...
A large portion of the earth’s surface is covered by soils and they are widely used as construction and foundation materials.
Specially soil mechanics is the branch of Engineering that deals with two main objectives ...
Investigation of the underground conditions at a site is prerequisite to the economical design of the substructure elements. It is also necessary to obtain sufficient information for feasibility and economic studies of the ...
This thesis abstract explores the utilization of soil as a readily available and abundant
resource for various applications, including cost-effective alternatives to traditional
construction materials. While ...
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 ...
In this study, the finite element method is used to investigate the variation and distribution nature of lateral earth pressure and displacement pattern behind a rigid cantilever wall. To provide resistance to overturning ...
The behavior of mechanically stabilized earth walls (MSE) with modular block facing and geosynthetic was investigated with numerical model that simulate progress of the wall, layer by layer until the desired wall height ...
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 ...
With a rapid growth of population in developing countries like Ethiopia, the constructions
of residential and commercial developments are booming in urban areas. New
developments are constructed adjacent to ...
The interaction of the soil with the structure has been largely explored with the assumption of material and geometrical linearity of the soil. Nevertheless, for moderate or strong seismic events, the maximum shear strain ...
In the last four to five decades piled raft foundations has been successfully applied in different parts of the world for optimization of civil engineering structure foundations. This thesis is an extension of research ...
Square isolated footings are widely used in practice. They may exist in close proximity at different depth with each other, this time designer must be aware of their influence upon one another. This leads to the overlapping ...
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 ...
Recently, geotechnical engineers have started to design the piled foundations more optimized by allowing a part of the pressure to be transferred directly from the raft to the ground. Such a foundation, where the raft and ...
