Safety protection technologies, including reinforcing existing running railway line track and bed, advance large pipe roofing and fullface grouting, are used in the construction of DK278+300~+380 section of Shijiazhuang tunnel on BeijingShijiazhuang passengerdedicated line crossing underneath ShijiazhuangTaiyuan running railway line, so as to avoid collapse and settlement of the railway bed and track of existing railway line and to guaranteed the safe running of the existing railway line. Conclusions drawn are as follows: 1) The construction program should be dynamically adjusted on basis of monitoring data. 2) The safety of the existing railway and the tunnel can be guaranteed by means of pertinent technologies.
