Download or read book Advanced Rail Geotechnology Ballasted Track written by Buddhima Indraratna and published by CRC Press. This book was released on 2023-08-14 with total page 467 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ballast plays a vital role in transmitting and distributing the train wheel loads to the underlying track substructure. The load-bearing capacity, safe train speed, and the levels of noise and vibration, as well as passenger comfort depend on the behaviour of ballast through particle interlocking and the corresponding deformation of this granular assembly. Attrition and breakage of ballast occur progressively under heavy and continual cyclic loading, causing track deterioration and rail misalignment affecting safety, while exacerbating the intensity of track maintenance. In the absence of realistic computational models, the track substructure is traditionally designed using mostly empirical approaches. In this book, the authors present the detailed information on the strength, deformation, and degradation aspects of fresh and recycled ballast under monotonic, cyclic, and impact loading using innovative geotechnical testing devices. A constitutive model for ballast incorporating particle breakage is presented representing a more realistic stress–strain response. The mathematical formulations and numerical models are validated using controlled experimental simulations and fully instrumented field trials. Revised ballast gradation is described to provide greater track resiliency and extended longevity. The book also provides a detailed description of geosynthetics for substructure improvement considering track deterioration caused by particle degradation, fouling, and impeded drainage. New to this second edition are extensive discussions on subgrade soil stabilisation, causes and mechanisms of soil fluidisation (mud pumping) under cyclic loading, and preventive and remedial measures to alleviate undue instability of ballast tracks. This book should prove most beneficial for final-year civil engineering students and for postgraduate teaching and learning. It is an ideal supplement for practising railway engineers and researchers engaged in the challenging tasks of future track design for heavier and faster trains.

This book was released on 2014-01-08 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: Involving several areas of geological engineering, geotechnical engineering and tunnel engineering, this book describes the soft soil deformation characteristics and dynamic responses induced by subway vibration load. Based on field monitoring and laboratory testing data, with both comprehensive micro-and macroanalysis, the authors present dynamic characteristics and deformation settlement of saturated soft clay surrounding subway tunnels using dynamic and static methodology. Mechanism of deformation, failure in microstructure of soft clay soil, dynamic response, macro deformation and settlement are all discussed and analyzed thoroughly and systematically. Some of the research findings in this book have been widely applied by large subway companies and will have broader application prospects in future. All the above make this book a valuable reference not only for technical engineers working in subway design or construction but also for advanced graduate students. Prof. Yiqun Tang works at the Department of Geotechnical Engineering, Tongji University, Shanghai, China.
Download or read book Rail Quality and Maintenance for Modern Railway Operation written by J.J. Kalker and published by Springer Science & Business Media. This book was released on 2013-04-18 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: In April 1990 a conference was held at the Cracow Institute of Technology, Cracow, Poland. The title of that conference was "Residual Stresses in Rails - Effects on Rail Integrity and Railroad Economics" and its themes were the measurement and prediction of residual stresses in rails, but, as the sub-title suggests, the intention was also to provide a link between research and its application to the practical railway world. At the Cracow conference there were 40 participants with 5 railways and 5 rail makers being represented and 25 papers were given. The Cracow conference was a success, and by March 1991 its off-spring, "The International Conference on Rail Quality and Maintenance for Modern Railway Operations", was conceived and birth was ultimately given in June 1992 at the Technical University, Delft. It turned out to be some baby, with 112 delegates from 24 countries taking part! As with its predecessor, the conference was to provide a forum for the exchange of ideas between research investigators, rail makers and railway engineers. A cursory examination of the list of participants suggests that about 57% were from the railway industry, 34% from universities and other research institutions and 9% from the steel industry. Bearing in mind that some of the railway industry participants were from their respective research and development organisations the balance of interests was about right.

Download or read book Track Access Charges in Freight Transport written by Justina Hudenko and published by Cambridge Scholars Publishing. This book was released on 2019-06-10 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: Given that there are still many unclear concepts, mutual contradictions and imperfections in methodologies used in the field of track access charging, this book acts as a communication tool for researchers, and discusses these charges with regard to rail freight competitiveness. It addresses four main topics: namely, the technical features of freight transportation and the costs incurred; the impact of incoherence and volatility of freight traffic volume; the market response to the track access charge level; and the influence of transport policy and state subsidies. The text will appeal to infrastructure managers around the world, especially those in networks where there is an intention either to facilitate the shift of freight to railways or to develop rail freight corridors. It illustrates that there are significant differences in the causation of costs on passenger and freight railways, and raises important questions that must be considered when communicating with consumers and the state.
