Vacationland


Book Description

Winner of the Western Writers of America 2014 Spur Award for Best Western Nonfiction, Contemporary Mention the Colorado high country today and vacation imagery springs immediately to mind: mountain scenery, camping, hiking, skiing, and world-renowned resorts like Aspen and Vail. But not so long ago, the high country was isolated and little visited. Vacationland tells the story of the region's dramatic transformation in the decades after World War II, when a loose coalition of tourist boosters fashioned alluring images of nature in the high country and a multitude of local, state, and federal actors built the infrastructure for high-volume tourism: ski mountains, stocked trout streams, motels, resort villages, and highway improvements that culminated in an entirely new corridor through the Rockies, Interstate 70. Vacationland is more than just the tale of one tourist region. It is a case study of how the consumerism of the postwar years rearranged landscapes and revolutionized American environmental attitudes. Postwar tourists pioneered new ways of relating to nature, forging surprisingly strong personal connections to their landscapes of leisure and in many cases reinventing their lifestyles and identities to make vacationland their permanent home. They sparked not just a population boom in popular tourist destinations like Colorado but also a new kind of environmental politics, as they demanded protection for the aesthetic and recreational qualities of place that promoters had sold them. Those demands energized the American environmental movement-but also gave it blind spots that still plague it today. Peopled with colorful characters, richly evocative of the Rocky Mountain landscape, Vacationland forces us to consider how profoundly tourism changed Colorado and America and to grapple with both the potential and the problems of our familiar ways of relating to environment, nature, and place.

Geosynthetic Reinforced Soil (GRS) Walls


Book Description

The first book to provide a detailed overview of Geosynthetic Reinforced Soil Walls Geosynthetic Reinforced Soil (GRS) Walls deploy horizontal layers of closely spaced tensile inclusion in the fill material to achieve stability of a soil mass. GRS walls are more adaptable to different environmental conditions, more economical, and offer high performance in a wide range of transportation infrastructure applications. This book addresses both GRS and GMSE, with a much stronger emphasis on the former. For completeness, it begins with a review of shear strength of soils and classical earth pressure theories. It then goes on to examine the use of geosynthetics as reinforcement, and followed by the load-deformation behavior of GRS mass as a soil-geosynthetic composite, reinforcing mechanisms of GRS, and GRS walls with different types of facing. Finally, the book finishes by covering design concepts with design examples for different loading and geometric conditions, and the construction of GRS walls, including typical construction procedures and general construction guidelines. The number of GRS walls and abutments built to date is relatively low due to lack of understanding of GRS. While failure rate of GMSE has been estimated to be around 5%, failure of GRS has been found to be practically nil, with studies suggesting many advantages, including a smaller susceptibility to long-term creep and stronger resistance to seismic loads when well-compacted granular fill is employed. Geosynthetic Reinforced Soil (GRS) Walls will serve as an excellent guide or reference for wall projects such as transportation infrastructure—including roadways, bridges, retaining walls, and earth slopes—that are in dire need of repair and replacement in the U.S. and abroad. Covers both GRS and GMSE (MSE with geosynthetics as reinforcement); with much greater emphasis on GRS walls Showcases reinforcing mechanisms, engineering behavior, and design concepts of GRS and includes many step-by-step design examples Features information on typical construction procedures and general construction guidelines Includes hundreds of line drawings and photos Geosynthetic Reinforced Soil (GRS) Walls is an important book for practicing geotechnical engineers and structural engineers, as well as for advanced students of civil, structural, and geotechnical engineering.

North American Tunneling: 2014 Proceedings


Book Description

The North American Tunneling Conference is the premier forum to discuss new trends and developments in underground construction in North America. With every conference, the number of attendees and breadth of topics grows. North American Tunneling: 2014 Proceedings reflects the theme for the 2014 conference, “Mission Possible.” The authors share new theories, novel innovations, and the latest tools that make what once may have been perceived as impossible, now possible. The authors of 128 papers share the latest case histories, expertise, lessons learned, and real-world applications from around the globe on a wide range of topics. They cover the successes and failures of challenging construction projects. Read about challenging design issues, fresh approaches on performance, future projects, and industry trends as well as ground movement and support, structure analysis, risk and cost management, rock tunnels, caverns and shafts, TBM technology and selection, and water and wastewater conveyance.
