Über dieses Buch

This book describes the second phase of the Qinghai–Tibetan railway construction project and is the first technological book discussing the geological routing of the Qinghai–Tibetan railway project on the “roof of the world.” Based on practical experience of railway construction work, it provides a substantial number of examples with detailed descriptions and conclusions. The complex geological environment of the Qinghai–Tibetan railway as well as the selection and optimization of the route are illustrated vividly and clearly with quotes, figures, photos, and tables. Connecting Golmud and Lhasa, it has a total length of 1142 km and at the Tanggula Pass has an altitude of 5072m—higher than any other in the world. A 960 km section is on a plateau at altitudes above 4000 m, and 550 km are in the permafrost region, making it the world’s longest and highest railway in the permafrost plateau region. The book is a model for the integration of theory and practice, making it a valuable reference source for civil engineering professionals working in geological routing in permafrost plateau regions, active fault zones, meizoseismal areas, nature reserves, and regions with geohazards such as steep slopes, sand and snow drifts and geothermal hazards.

Chapter 1. Introduction
Abstract
With unique geographical position and severe natural condition, Qinghai–Tibet Plateau has also developed various unfavorable geological phenomena, and these geological problems bring many impacts to the Qinghai–Tibet Railway line selection. In this chapter, main engineering geological problems along Qinghai–Tibet Railway and principles of railway line selection under different geological conditions are summarized.

Chapter 2. The Qinghai–Tibet Railway Geological Environment
Abstract
The environmental conditions along the Qinghai–Tibet Railway are extremely harsh, the ecology fragile, and the geological conditions complex, complicating the design and construction of the railway line. Therefore, a comprehensive analysis of the various engineering geological conditions along the line is essential for studying the line scheme. In this chapter, the geographical conditions—namely the geography, climatic characteristics, soil and vegetation, wildlife, river systems, and ecological environment—along the Qinghai–Tibet Railway are discussed. Moreover, the geological environment—the topography, formation lithology, geological structure, hydrogeology, seismic and active faults, permafrost distribution, and unfavorable and unique geology—along the railway is described in detail.

Chapter 3. Geological Line Selection in Permafrost Regions
Abstract
Permafrost can adversely affect railway projects and can induce major disasters, such as roadbed frost heaving and thawing settlement. This chapter discusses the principles of geological line selection in permafrost regions, the classification of frozen soil and its engineering-geological properties, and the major engineering-geological structures in the permafrost regions along the Qinghai–Tibet Railway.

Chapter 4. Line Selection in Active Fault Zones and Meizoseismal Areas
Abstract
This chapter discusses the spatial distribution of the Kunlun Mountain, Bengcuo, and Yambajan–Damxung–Gulu seismotectonic zones and explains the relationship between active faults and earthquakes, which can severely damage railway structures. The line selection and engineering properties of the Qinghai–Tibet Railway in high-intensity earthquake zones and active fault zones are implemented not only as per the geological-engineering line-selection principles for high-earthquake-intensity regions but also considering the railway safety, reliability, and cost.

Chapter 5. Railway-Line Selection in Slope Areas
Abstract
The main mountain areas along the Qinghai–Tibet Railway are Kunlun Mountains, Hoh Xil Mountains, Fenghuo Mountain, Kaixinling, and Tonglha Mountains, along the slopes of which are distributed various unfavorable geological hazards. Route selection and optimization are crucial in minimizing their adverse effects on the construction of the Qinghai–Tibet Railway.

Chapter 6. Route Selection in Nature Reserves
Abstract
The Qinghai–Tibet Railway passes through not only urban areas but also several nature reserves, and its construction and operation substantially affect its the social and ecological environment along the line, which renders crucial the balancing of human activities and the environment. This chapter details the route selection in the nature reserves: Sects. 6.1 and 6.2 overview the major nature reserves along the railway and the location of the railway relative to the nature reserves, respectively. Sections 6.3 and 6.4 describe the principles that should be followed in route selection in nature reserves, and Sect. 6.5 explains the effects of the railway on the environment and presents the main solutions.

Chapter 7. Railroad Route Alignment in Geothermal, Aeolian, and Snowdrift Areas
Abstract
Geothermal activity, dust storms, and snowdrift severely affect railway lines. Rich geothermal resources, plateau desertification, local-area development, semi-fixed and shifting sand dunes, and heavy snow are common along the Qinghai–Tibet Railway. Given these phenomena, geological line selection in the Qinghai–Tibet Plateau warrants attention.
