PARAMETRIC STUDY OF PILED-RAFT FOUNDATION ONHOMOGENEOUS DRAINED STIFF CLAY SOIL USINGFINITE ELEMENT METHOD-ABAQUS SOFTWARE

TEZERA, TADILO (2020)

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 ...
Investigating the Failure of Cut Slope Using Numerical Methods: the Case of Arib Gebeya - Beshello - Mekdela Amba Rural Road, Diyo

Misgan, Bikis (2020)

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, ...
Analysis of Piled Raft Foundation Subjected to Lateral and Vertical Loading using FLAC3D

Worku, Mulat (2020)

Due to the complex nature of the piled raft foundation, its realistic design relies on the more rigorous computer based methods using either finite element or finite difference based soft wares. This study develops a ...
CORRELATION OF UNCONFINED COMPRESSIVE STRENGTH WITH INDEX PROPERTIES OF SOILS FOUND IN DIASPORA, BAHIRDAR

MESKEL, BIRHAN- (2020)

Correlations are important to estimate engineering properties of soils particularly for project where there is a financial limitation, lack of test equipment or limited time. Although correlations are commonly used in the ...
EFFECT OF EXPANSIVE SOIL ON LIGHT WEIGHT STRUCTURES OF GONDAR TOWN FROM CONSTRUCTION, GEOTECHNICAL AND STRUCTURAL PERSPECTIVE

BIYADGLIGN, SERAWIT (2020)

The amount of damage caused by expansive soils is alarming. Damages sustained by structures include distortion and cracking of pavements and on-grade floor slabs; cracks in grade beams, walls, and drilled shafts; jammed ...
Static and Pseudo Static Analysis of Retaining Wall Located In ‘Harego’ Site Using Finite Element Method

Teshome, Birhanu (2020)

In this study, analysis of retaining wall and backfill soil effect using a finite element based software; PLAXIS 2D version 8.5 for the inclined cohesion less backfill effect was conducted. The soil sample taken from site ...
Eucalyptus Wood Ash As Stabilizer for Black Cotton Soil

SHITAYE, HAYLEMARIAM (2020)

This research is aimed at evaluation the suitability of wood ash for use in stabilization of expansive black cotton soil. Laboratory work was conducted to determine various geotechnical properties of soil sample and the ...
THE SCHOOL OF GRADUATE STUDIES , BAHIRDAR INSTITUTE OF TECHNOLOGY , IN FULFILLMENT OF REQUIREMENT FOR DEGREE OF MASTER OF SCIENCE IN CIVIL ENGINEERING UNDER GEOTECHNICAL ENGINEERING

ADUGNA, FENTAHUN (2020)

The Lalibela ashuda zibest Fendika road, linking Jawi with Durbetie towns traverses through one of the most difficult mountainous ranges in Ethiopia. Slope instability problems in the form of rock fall, rotational failure ...
In Partial Fulfillment of the Requirement for the Degree of Master of Science In Geo-Technical Engineering

Yohannes, Kidusu (2020)

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. ...
ANALYSIS OF BEAMS AND STRIP PLATES ON IMPROVED CONTINUUM-BASED SUBGRADE MODELS, THE FINITE DIFFERENCE APPROACH

SILESHI, BETELHEM (2020)

Soils do not behave as elastic solids, but elasticity theory is widely used to compute stresses and displacements in soil profiles. Different subgrade models have been proposed by many researchers for problems of beams ...
EXPANSIVE SOIL GEOTECHNICAL PROPERTIES STABILIZED WITH PLASTIC POWDER AND LIME

Mulu, Mahider (2020)

Expansive Soil Geotechnical Properties Stabilized with Plastic Powder and Lime Expansive soil is considered defective due to the large volume change it undergoes for any moisture fluctuation. There are several engineering ...

Moges, Melkamu (2020-01)

SWCC of Unsaturated Tropical Weathered Residual Soils Appropriate for a Range of Index Properties Using Pressure Plate Apparatus. Tropical weathered residual soils are used as construction material for a different ...
Swcc of Unsaturated Expansive Soils Appropriate For Range Of Index Properties Using Pressure Plate Apparatus

Amlak, Temesgen (2020-02)

SWCC of Unsaturated Expansive Soils Appropriate for a Range of Index Properties Using Pressure Plate Apparatus Knowledge about engineering properties of soil in a specific area is necessary to provide information on the ...
EVALUATING SHRINK SWELL CHARACTERSTICS OF EXPANSIVE SOILS IN SOME AREAS OF AMHARA REGION

Mekonen, Belaynesh (2020-03-11)

The research is mainly determining the degree of expansiveness and shrinkage swell characteristics of soils in some areas of Amhara region. Accordingly, several data were taken from design office and from theses that ...
Numerical Investigations on the Behavior of Piled Raft foundation on medium Dense Sand with Finite Difference Method

Belete, Birhanu (2020-03-15)

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 ...
USE OF TEXTILE INDUSTRYFACTORY WASTE ASH ON BLACK COTTON SOIL IMPROVEMENT USED AS SUBGRADE MATERIAL (CASE IN BAHIR DAR TOWN)

DEJENE, BRUKTAWIT (2020-03-15)

Expansive soils, such as black cotton soils, are basically susceptible to detrimental volumetric changes, with changein moisture content. The cyclic wetting and drying process causes vertical movements in expansive soils ...
Numerical Investigation of the Dynamic Response of Pile Embedded in Sandy Soil Subjected to Vertical Dynamic load

Gebeyehu, Getahun (2020-03-15)

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 ...
