| Abstract: | Xiaguanying to Guangyuan part of the Lan-Yu Railway,as the Tibetan Plateau to northeast keep expanding and crush,the formation lithology changes a lot and the geologic structure is very complicated,The high or sky-high earth stress makes it vulnerable to big transmogrification.Parameters of anchor-plate retaining is optimized,the construction method is improved,to release stress before construction,etc.which ensures construction safely. |

| Keywords: | railway tunnel thin layer of carbonaceous slate high In-situ big transmogrification stress release |
