Abstract

Abstract: By using numerical experimental models, the support characteristics of steel arch bolt shotcrete initial support structure and W-shape steel strip bolt shotcrete initial support system in grade IV surrounding rock of soft ground highway tunnels were compared and analyzed. Experimental sections were carried out in grade IV weak surrounding rock to compare the support effects of W-shape steel strip bolt shotcrete support structure and steel arch bolt shotcrete support structure in soft ground highway tunnels. The results showed that the use of W-shape steel strip bolt shotcrete support structure has the same good support effect as steel arch bolt shotcrete support structure in soft ground highway tunnels. The implementation of W-shape steel strip bolt shotcrete support structure can better exert the self-supporting capacity of surrounding rock, but its restrained deformation amplitude is weaker than that of steel arch, which can provide reference for the selection of support structure types for highway tunnels with similar geology.
