The New York Times Bestseller! The story of an outcast boy, his eccentric dad, and the scary underground world they discover through secret TUNNELS. 14-year-old Will Burrows has little in common with his strange, dysfunctional family. In fact, the only bond he shares with his eccentric father is a passion for archaeological excavation. So when Dad mysteriously vanishes, Will is compelled to dig up the truth behind his disappearance. He unearths the unbelievable: a secret subterranean society. "The Colony" has existed unchanged for a century, but it's no benign time capsule of a bygone era--because the Colony is ruled by a cultlike overclass, the Styx. Before long--before he can find his father--Will is their prisoner....

The need for a single reference book of recommendations and guidance for tunnel lining design has long been recognised. In partnership with the Institution of Civil Engineers Research an Development fund, The British Tunnelling Society (BTS) considered that the valuable knowledge and experience of its members on tunnel lining design should be made available to the wider international underground construction industry. Tunnel lining design guide is primarily intended to provide those determining specifications of tunnel linings with a guide to the recommended rules and practices to apply in their design. In addition, it provides practitioners who procure, operate, or maintain tunnels, along with those seeking to acquire data for use in their design, with details of the factors that influence correct design, such as end use, construction practice and environmental influences.

This work illustrates how the Analysis of Controlled Deformation in Rocks and Soils (ADECO-RS) is used in the design and the construction of tunnels. This is a very new and effective way of tunnel construction. The ADECO-RS approach makes a clear distinction between the design and the construction stages and allows reliable forecasts of construction times and costs to be made. It uses the advance core (the core of ground ahead of the face) as a structural tool for the long and short term stabilisation of tunnels, after its rigidity has first been regulated using conservation techniques.

Go behind the scenes into little-known corners of the public record and discover how corporate America has worked hand-in-glove with the Pentagon for decades -- dreaming about, planning, and actually constructing secret underground bases. And newly-uncovered information indicates that the strangeness continues with bizarre, high-tech gadgets like portable, hand-held surgical lasers and injectable electronic IDs as small as a grain of rice!

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

Never before has the Earth, centuries in its development, been within seconds of total annihilation. Captain Alexi Romanoff, a Slovanian astronaut and inventor of a telescope that can x-ray the insides of any heavenly body focused within its sight, discovers a geological phenomenon beneath the earth’s surface. They are tunnels. They travel all over the globe, connecting the vast expanses of the earth. If used in good faith, they could potentially aid humankind in incalculable ways. If manipulated with evil intent, they could be twisted into a weapon of mass destruction. Josef Janos possesses that very evil intent. As a child, he watched as his parents were viciously slaughtered during the bloody Slovanian revolution. In exile, he has anxiously awaited the opportunity to unleash his revenge. Accompanied by six other deposed tyrants, and with access to enough gold to buy anyone's ethics, Josef Janos is about to have his day.
