Abstract：Based on the experience of existing railway tunnel engineering and in view of the typical complex geological conditions such as large deformation of soft rock with high crustal stress,rock burst,active fault zone,high ground temperature,and high-pressure water-rich fault,this paper analyzes the characteristics of railway tunnel and puts forward the technical solutions for construction.Relevant technical solutions for construction are of referential value for Sichuan-Tibet Railway tunnel construction.
