First published in 1990 and based on sources not available for Paul Brickhill's earlier work, the book tells how on the night of March 24, 1944, seventy-six Allied POWs slid through a 350-foot tunnel and out of a high-security German prison camp, into history.
Transportation Tunnels, 2nd Edition provides a comprehensive text on tunneling and tunnel engineering applicable in general to all types of tunnels, with more detailed information on highway and railway tunnels. While the First Edition of the book was confined to deal with railway and highway tunnels, the Second Edition is also extensively considering the latest trends in use of tunnels in different other fields. The book has been revised to provide coverage of water conveyance, navigation and material conveyance tunnels also and deals with these subjects in more detail. It covers all aspects of investigation, design, construction, monitoring and maintenance of tunnels. Special emphasis has been laid on the geotechnical investigations, interpretation of findings and relating the same to the design as well as the construction of tunnels. The book reflects the advancements in the knowledge of ground behaviour and rock mechanics and also in construction technology, including use of TBM in the last two decades. It covers in sufficient detail the basic requirements of tunnel profile, the geometric parameters, clearance requirements, aerodynamics, and cost economics in fixing alignments with different design parameters like curvature, gradient and operational requirements. It discusses in detail alternative forms of the cross section / profile and illustrates design methodology with examples. The different methodologies that have been used in the past using timber or steel supports by stage wise expansion of cross sections and modern methodologies used for boring full profile using new tunneling methods and Tunnel Boring Machines are also comprehensively discussed. Requirements of tunnels in respect of ventilation, lighting and drainage are adequately covered. Separate chapters have been included on ‘Instrumentation’ and ‘Tunnel Inspection and Maintenance’. The expanded text on the use and advantages of methodologies and equipment for dealing with various aspects of construction of tunnels is based on observations through site visits, discussions with, and experiences of people as recorded on large number of tunneling works which have been taken up recently for railways, highways and urban transport subway projects. The book can serve as a textbook for undergraduate and graduate students and as a reference book for practicing engineers.
Immersed tunnels have been around for more than a century but remain a relatively unknown form of tunnel construction. For waterway crossings they are an effective alternative to bored tunnels and bridges, particularly in shallower waters, soft alluvial soils, and earthquake-prone areas. Successful implementation requires a thorough understanding o
This text describes topics discussed at the conference, including: tunnelling and construction in soft ground and rocks; geological investigations; tunnelling machines; planning for underground infrastructure; safety issues and environmental and social aspects of underground development.
The book describes the details about the tunnel construction, that includes, history, shape and sizes, various conventional methods, techniques, planning, designing and methodology of construction in Indian context. The geological investigation for the selection of most economical, and technically viable, alignment for transportation. Further book highlights the necessity of safety for men, material and machinery, during construction. The Geo technical investigation reports are prepared, Rock is classified in five classes like good rock, poor, fair, poor and very poor, according to the strength and characteristics of the rock the conclusion and recommendation are followed while designing the tunnel with adequately safe and sound tunnel support system. ‘The book emphasises on engaging skilled, experienced and trained workmen, plant and equipment in good service condition, which is very important for the completion within stipulated time and cost. The principle of reduce, reuse and recycle is applied in all possible construction activities to minimise the risk to the environment. For ensuring this, the temporary and permanent support system are designed to provide adequate support for the excavated tunnel profile. The Geo technical instrumentation is also provided to continuously monitoring the profile, foresee the behaviour of Rock mass, so that preventive steps are taken in time to mitigate the threats posed by fractured rock mass or poor rock. Finally, it illustrates the various detailed activities and sequences involved at macro level and micro level, for the construction of a tunnel.
Engineering Geology is a multidisciplinary subject that interacts with other disciplines, such as mineralogy, petrology, structural geology, hydrogeology, seismic engineering, rock engineering, soil mechanics, geophysics, remote sensing (RS-GIS-GPS) and environmental geology. This book is the only one of its kind in the Indian market that caters to the students of all these subjects. Engineers require a deep understanding, interpretation and analyses of earth sciences before suggesting engineering designs and remedial measures to combat natural disasters, such as earthquakes, volcanoes, landslides, debris flows, tsunamis and floods. This book covers all aspects of engineering geology and is intended to serve as a reference for practicing civil engineers, geotechnical engineers, marine engineers, geologists and mining engineers. Engineering Geology has also been designed as a textbook for students pursuing undergraduate and postgraduate courses in advanced/applied geology and earth sciences. A plethora of examples and case studies relevant to the Indian context have been included for better understanding of the geological challenges faced by engineers. New in this Edition • The concept of watershed and the depiction of watershed atlas of India • Latest findings by the Indian Bureau of Mines • Recent developments in coastal engineering and innovative structures • New types of protective structures to guard against tsunamis • Role of geology in building smart cities • Environmental legislation in India

Describing and detailing the boring of major railroad tunnels throughout Canada, the United States, and Mexico, this book covers the period from the creation of Virginia's Blue Ridge Tunnel in the 1850s to Copper Canyon's Continental and El Descanso tunnels in the early 1960s. Other notable tunnels featured here include Massachusetts' notoriously expensive and slow-progressing Hoosac Tunnel; Colorado's rail and water Moffat Tunnel; Montana's Flathead Tunnel; and several major tunnels along the Canadian Pacific's main line. In addition to providing details on the tunnels, the author considers the reasons they were created, their engineers, and their use. The book includes more than 50 period and contemporary photos. A glossary explains concepts related to railroad construction and maintenance.
