Abstract Determining the types and parameters of advance support is an important work in tunnel construction under conditions of unfavourable rocks. In this research，the determination of advance support for tunnel was established，including the safety assessment of construction，the modes election and the parameter determination of advance support. The predicted deformation value of surrounding rock of tunnel and the value from control standard were compared to determine whether the advance support was required. The engineering analogy was used to determine the modes of advance support under the condition that the predicted deformation value adopting the selected mode of advance support meets the control standard. The sensitivity and effectiveness of support parameters were analyzed to determine the upper and lower bounds of the support parameters. The method has been successfully applied in shallow covered Hejie high-speed railway tunnel.

Key words： tunnelling engineering advance support support parameters deformation control
