    Research on Construction Technology of Shallow-Buried and Long-Span Railway Tunnel in Soft Rock

    New search for: Huang, Nan Qing

    Based on the construction of the New Yangshi Tunnel, a section of the electrified speed-up reconstruction project in Zhe-Gan Railway, the author discusses and studies the construction technology employing annular excavation with core soil reserved method, together with the use of H175 steel frame as initial support in the shallow-buried and long-span railway tunnel in soft rock. Through the technical and economic comparison, it shows that the present method is faster, with the construction progress of 50m per month in average, and is more economical in construction than Center Diaphragm (CD) method with an investment of 4,000,000 Yuan having been saved.
