Tiger Ridge summary of the preliminary design of road tunnels with rapid economic development, traffic engineering has become a powerful driver of economic development and support. With the advance of highway construction, transportation infrastructure has continued to deepen, the current highway tunnel project has become an important part of the system. Its optimal road alignment, reduce highway mileage have a significant impact; while the surrounding area to promote environmental protection, economic development and national defense also has far-reaching impact. Tiger Ridge Road, Hua County, Shaanxi Province is located within the tunnel, is even Huo expressway Xi'an, Shaanxi Tongguan line segment. Tiger Ridge is located in the south of the tunnel starting at Lee Mizoguchi, end at the Tiger Ridge at the northern foot of leeks Mizoguchi, tunnel length of 1780m. In this paper, the tunnel planning, design and calculation are discussed in detail. Design of the main contents are: tunnel survey, rock classification, topography and geological surveys, meteorological investigation, tunnels linear design, vertical, cross-sectional design, the hole and Portal design, lining structural design, structural calculations, water and drainage, ventilation design and operation of lighting design. When the tunnel alignment took into account topographic and geologic conditions, in the lining of the calculation, consider the elastic reaction force of the existence of the tunnel planning and design process to follow the tunnel full functionality, security, economic development of the basic principles of the tunnel to complete the preliminary design of the tunnel . The final design results include: design manual part, rock lining calculations, operating ventilation calculations, operating lighting calculations, route plan, longitudinal design, construction limits and within the contour map, Portal design and Myeongdong, Ⅳ class rock lining design, fans, lighting diagram. Keywords: tunnel; structural calculations; lining; waterproofing and drainage; ventilation; lighting
