| Abstract: | Loess is widely distributed in the western region of our country, with its special characteristics in the engineering. With the large-scale railway construction in the western region, there are more and more geographical problems in the collapsible loess engineering. The inappropriate treatment of these problems will influence the construction and the railway＇s safe operation. Combined with the large-sectional railway loess tunnel construction in Zhengzhou-Xi＇ an PDL, this paper introduces the construction techniques for large-span railway tunnels in the loess regions, including the excavation, support, prevention and drainage of water. |
