12111. Assessment Of Potential Causes Of Construction Delay In Tunnels A Case Study At Awash-weldiya Railway Project
Extensive investments in transport are currently being carried out in Ethiopia. A substantial partrnconsists of railway projects with some underground/tunnel constructions.rnThis research deals with assessment of potential causes of construction delay in tunnels; a casernstudy at Awash-Weldiya...
12112. Thermo-mechanical Analysis Of Railway Wheel Rail Rollingsliding Contact
Thermal damage caused by frictional heat of rolling-sliding contact is one of the most importantrnfailure forms of wheel and rail. The coupled mechanical–thermal behavior of wheel and railrnmaterials under rolling contact is studied to determine the temperature rise due to the...
12113. Improving Compressive And Tensile Strength Of Slab Sleepers For Railway Bridge By Mechanism Of Steel Fiber Reinforced Concrete
Concrete is a material that needs strengthening in tension in order to meet the structuralrnrequirements. New techniques of strengthening concrete, besides the usual ordinaryrnreinforcement bars, are developing; fiber reinforced concrete is one of them. Fibrernreinforcement is a method that has...
12114. Wear Rate Analysis Of Overhead Line Contact Wire By Considering Current Effect Using Ansys.
The overhead line and pantograph is the two contacting bodies Wear on overhead line is one of the greatest problems in the railway industry. To overcome the problem of wear on overhead line different studies have been made. A better material selection that can withstand material loss due to sliding...
12115. Developing A Material For Improving Fatigue Strength Of Welded Bogie Frame Of Addis Abeba Light Rail Transit
This research paper present develops a material for improving the fatigue strength of the bogie frame of AARLT. The purpose of this research is to compare between the current material and selected material in order to protect the bogie frame from failure. In the analysis of the research ANSYS and...
12116. Adaptation Of Station Design Parameters For Addis Ababa Light Railway In Ethiopian Context
Station is a basic production unit of railway transportation, integrating technical equipment relating to transportation. For the last couple of years investigations have been conducted in Ethiopia in railway site selection. One of that is the Addis Ababa light railway, where two alternative rights...
12117. The Influence Of Heat Treatment On Wheel And Railwear
Wheel and rail is one of the most important material used to support and guide rail vehicle safelyrnand smoothly. Since wheel and rail suffers from various interacting mechanical and thermalrnforces, friction modifiers, various contaminants and environmental atmosphere, wear poses largernproblem on...
12118. Deformation History And Geochemistry Of Neoproterozoic Rocks Of Tahtailogomti Area Tigrai Northern Ethiopia
The Tahtai Logomti area is dominated by the Neoproterozoic basement rocks of Northern Ethiopia, occurred between the Adwa and Mai Kenetal blocks and covered by metavolcano-sedimentary rocks which belong to the Tambien and Tsaliet Groups and are part of the Arabian Nubian Shield. In this study, the...
