China's Loess to wide distribution, thickness, stratigraphic sequence complete, clear and known for its ancient soils in the world. Especially in the west Wushaoling, the Taihang Mountains to the east, north of the Great Wall, south of the Qinling Mountains in the middle reaches of the Yellow River, the surface was almost entirely covered by loess, for the distribution area of 440,000 km2, the formation of the strata in a row, thickness, area Canton, the magnificent landscape in the Loess Plateau, the world rarely seen. Loess often with different direction and structure of the original joint, in particular the joint development of vertical and has a certain continuity, porosity, loose structure, loose, low-density; between the loess grain structure so that the water easily loess collapse, falling more A collapsibility. Loess large section of tunnel construction, soil damage to the region, is usually more difficult to form a load-bearing arch, and vulnerable to landslides before the collapse of no omen; relatively shallow depth of the tunnel, easy to produce strong construction surface seam. In the area of the tunnel project, depending on the loess tunnel for the adverse geological problems. High-speed railway is an important symbol of railway modernization, in the face of the West Zheng high-speed dedicated passenger railway tunnel loess brought about by technical problems and challenges, the Ministry of Railways building management, design, construction, and scientific research institutes, such as joint research, using theoretical analysis, Indoor test, field test, and other means of a comprehensive, in the Loess rock engineering properties, design, construction techniques and the many scientific issues has made significant progress, and won, "Mr West Line passenger large section of loess tunnel construction methods and monitoring technology," " Mr West Line passenger large section of loess tunnel reasonable support parameters and surface subsidence control technology "and" Mr West Line passenger large section of loess tunnel cracks in the surface control technology "and so on a number of research results. Loess large section of the tunnel construction to explore a range of research, construction technology and construction management for the West Zheng passenger yellow line to the success of building the tunnel has made a positive contribution to the enrichment and development of China's Loess tunnel construction technology, to promote our country and the world Tunnel construction technology. The book summary of the engineering properties of loess wall, a wall of loess detailed classification to meet the 350km / h high-speed railway tunnel and the structure of the reasonableness of the requested size of the tunnel section, and in the form of parameters, load characteristics of the loess tunnel wall, Anchor role in the stability of the characteristics of the tunnel and control the key technology design. Summed up the loess cave-in of the tunnel, ahead of support, methods of excavation, support, waterproof, and the lining of the tunnel collapse loess of the basement to deal with security systems such as construction technology, large sections of loess through the tunnel under the existing structure of railways, highways, and other buildings Construction Deformation Control Technology. Loess revealed the characteristics of environmental pollution inside the cave, tunnel construction, tunnel construction loess formation mechanism of the surface cracks and cracks in the law, to prevent harmful propose the construction of the surface cracks control standards, and dealing with surface Cracking control technology. Introduced the loess tunnel construction technology and management experience, but also introduced the loess landslides dealing with the tunnel construction techniques. The book reflected the loess tunnel system design, construction and management of knowledge and experience in both theory and practice, rich in content and the amount of information, knowledge structure of the system.用翻译器翻译的，但希望对你有帮助~！
