| Abstract: | Loess soil has the characteristics of being porous in nature, low in density, and prone to collapsing with water. It will usually have some effect on the construction and the safe operation of the railway to build tunnels in loess areas. With the construction practice of the Zheng-Xi Special Passenger Railway as a practical example, the key construction techniques for large-sectioned railway tunnels in loess areas, such as excavation, propping up, and water-proofing and draining, are dealt with in the paper, which provides corresponding experience for the solution of construction problems in building large-sectioned railway tunnels in loess areas. |
