Abstract：
In order to quantitatively determine the initial support parameters in a highway tunnel construction, somefinite element layer-structure modelswith different steel support spacingas optimization parameters, including shotcrete, anchor and plastic zone of surrounding rock, are researched and numerical simulation calculation and optimization resultsfor initial support parametersare given in the paper, based on the geological forecast by the geological radar and checking of the bearing capacity of the initial supports, the effectiveness of the proposed method is verified by field monitoring results.
