摘要：

Large deformation of soft rock tunnel has been one of significant problems in the railway construction in Northwestern China. The main causes led to the problem are large depth with high crustal stresses, soft rock with strong anisotropy and quick excavation. The paper is to introduce the large deformation of the slate-schistose rock tunnel in Lan-Yu railway construction, the essential factors affecting the deformation of carbonaceous slate tunnel including geological stress, special properties of the rock and its soften mechanism caused by excavation, rock pressure and its strengthening effect; some lessons from the geological investigation and design of tunnels.
