Links Geotechnics with Railway Track Engineering and Railway Operation Good railway track and railway operations depend on good geotechnics, in several different ways and at varying levels. Railway Geotechnics covers track, track substructure, load environment, materials, mechanics, design, construction, measurements, and management. Illustrated by case studies, with an emphasis on the geotechnical aspects of railway engineering, it discusses these topics from a historical perspective. It also presents the methodologies and best practices developed over the past 20 years. Written by Four Experienced Professionals This book: Emphasizes the practical aspects and best practices for railway track and substructure Contains guidelines for design, construction, and maintenance of railway track and substructure Provides many examples and case studies Railway Geotechnics is written primarily for professionals and graduate students, and begins with the fundamentals and basic principles, leading in to practical applications. The authors bring considerable experience and expertise, with many years of research and development, academia, railway operations, and consulting.
In this book, the authors discuss testing of ballast, including the strength, deformation and degradation aspects of fresh and recycled ballast under monotonic and cyclic loading. The effectiveness of geosynthetics in stabilising recycled ballast has also been examined. A new stress-strain constitutive model for ballast incorporating particle breakage is presented. Finally, a new range of particle gradations, balancing the strength and permeability requirements, has been proposed for future rail tracks. This book is intended as a reference text for final year civil engineering students and postgraduates, and for practicing railway engineers with the task of modernizing existing designs.
Highways provide the arteries of modern society. The interaction of road, rail and other transport infrastructure with the ground is unusually intimate, and thus needs to be well-understood to provide economic and reliable infrastructure for society. Challenges include not only the design of new infrastructure (often on problematic ground), but increasingly the management and maintenance of aging assets in the face of issues such as climate change. This book is the written record of the first International Conference on Transportation Geotechnics held under the auspices of the International Society of Soil Mechanics and Geotechnical Engineering, held in Nottingham, UK, in 2008. It comprises about 100 papers from a global selection of researchers and practitioners on: – Slope instability, stabilisation, and asset management; – Construction on soft ground; – Interaction with structures and geogrid reinforced soil; – Effect of climate change and vegetation; – Highways, pavements and subgrade; – Railway geotechnics; – Soil improvement; – Characterisation and recycling of geomaterials. A further part of this collection contains papers on unbound aggregate materials as used in pavement construction and drainage. They formed the ‘Unbound Aggregates in Roads (UNBAR7)’ theme of the conference which followed on from the previous symposia of that title, also held in Nottingham, UK, most recently in 2004. The volume will be of interest to professionals and academics in geotechnical, highway, railway and general civil engineering.
Design and Construction of Pavements and Rail Tracks - Geotechnical Aspects and Processed Materials is a compilation of selected contributions produced between 2002 and 2005 by the International Committee TC3 - Geotechnics of Pavements of the International Society of Soil Mechanics and Geotechnical Engineering (ISSMGE), a committee dedicated to gathering current knowledge of geotechnical aspects relating to pavements and rail tracks. The volume presents advanced procedures for laboratory and field materials characterization, including processed materials (non-conventional road construction materials), novel tests for field stiffness evaluation, a pre-standard for roller integrated continuous compaction control and new theories for evaluation of the long term performance of materials, including environmental aspects. These contributions represent the latest developments relating to the design, construction and long term performance of pavements, rail tracks and earth structures, with emphasis on the geotechnical and environmental background.
Advances in Transportation Geotechnics II deals with the geotechnics of roads, railways and airfields. Providing economic and sustainable transportation infrastructures for societies is highly dependent on progress made in this field. These contributions to the 2nd International Conference on Transportation Geotechnics (Hokkaido, Japan, 10-12 September 2012), held under the auspices of the International Society of Soil Mechanics and Geotechnical Engineering (ISSMGE), cover a broad range of technical topics, including those addressed by the first conference held in Nottingham, UK in 2008. Advances in Transportation Geotechnics II contains a total of 138 reviewed papers from 29 countries in addition to 5 invited papers prepared by distinguished keynote lecturers, and addresses the following themes: - Geotechnics of pavements, railway tracks and airfields; - Geomaterial, including non-traditional materials; - Asphalt mixtures and hydraulically-bound materials; - Earthworks for transportation facilities; - Application of geosynthetics; - Laboratory testing and in-situ testing; - Modeling and numerical simulations; - Design, construction and maintenance; - Performance evaluation and quality control; - Sustainability of management and rehabilitation; - Risk assessment and environmental issues. Advances in Transportation Geotechnics II will be of interest to professionals and academics involved in geotechnical and pavement engineering of roads, railways and airfields.
"Advances in Environmental Geotechnics" presents the latest developments in this interdisciplinary field. The topics covered include basic and advanced theories for modeling of geoenvironmental phenomena, testing and monitoring for geoenvironmental engineering, municipal solid wastes and landfill engineering, sludge and dredged soils, geotechnical reuse of industrial wastes, contaminated land and remediation technology, applications of geosynthetics in geoenvironmental engineering, geoenvironmental risk assessment, management and sustainability, ecological techniques and case histories. This proceedings includes papers authored by core members of ISSMGE TC5 (International Society of Soil Mechanics and Geotechnical Engineering---Environmental Geotechnics) and geoenvironmental researchers from more than 20 countries and regions. It is a valuable reference for geoenvironmental and geotechnical engineers as well as civil engineers. Yunmin Chen, Xiaowu Tang, and Liangtong Zhan are Professors at the Department of Civil Engineering of Zhejiang University, China.
Increasing environmental awareness has emphasised the many engineering situations in which there are potential environmental impacts (both harmful and beneficial). This book provides engineers who are (or are likely to be) involved in such projects with the information and techniques to enable them to select a course of action which is 'best practice' from both the environmental and engineering points of view. The author outlines the fundamental principles of geotechnics and current ground engineering practice and proceeds to a detailed examination of the interaction with the environment. Environmental Geotechnics amalgamates the current body of knowledge on environmental aspects of ground engineering including landfill and contaminated land and as such will appeal to engineers working in the fields of geotechnics, the environment and water, waste management, and geology.
