| dc.description.abstract | A railway track will deteriorate when exposed to repeated traffic loadings and with it, track alignment changes and track level settlements will also occur on selected areas of a given stretch. This irregularity created due to repetitive use of the system will shorten the intended service life of the track components unless elements that induce deteriorating effects are studied and monitored well. This research focuses on the study of the root causes of uneven settlements of a ballasted railway track system. The study will investigate into identifying what the frequent causes of differential settlement of ballasted railway tracks are. After assessing the basis of this condition, the impact uneven settlement has on the track system will be surveyed with the help of extensive literature review of studies made about similar cases. Alongside this, in order to fully understand and quantify the settlement behavior of the track system, the proposed approach will be to model the existing ground condition of the track system (using track component material properties) using a computer programmed tool named ABACUS and analyze the anticipated settlement behavior of a selected sampled section under investigation. The findings of this study will be the derivation of profile characteristics of sample potentially differentially settling section in the Addis Ababa Railway Transit line and thus show that specific area of the transit line need frequent inspection due to its unique behavior. | en_US |
