Mechanized supporting construction technology and key construction of railway tunnels Technical Research

Taking the III. and IV. grade surrounding rock construction section of Loushan Tunnel in Xinbin County, Fushun City, Liaoning Province as an example, mechanized supporting construction is carried out on the tunnel construction section. The design of the construction technology and the development

high-speed railway tunnel

Application of Mechanized Construction Method to Large Cross-sectional Tunnel with Soft Surrounding Rocks

The construction technology of mountain tunnel in China is under-developed. Hence,the mechanized construction method for large cross-sectional tunnel on high-speed railway is introduced. A new kind of tunnel construction organization mode with four tunnel construction lines,i.e. excavation,support
