Groundwater infiltration into tunnels causes water to percolate through the fissure channels in initial support shotcrete. This results dissolution and outflow of calcium hydroxide, a key product cement hydration. process significantly incurs formation crystallization blockages tunnel drainage systems. Optimizing shotcrete mixing ratio is feasible way mitigate these blockages. Therefore, this study conducts tests investigate impact six admixtures, namely, antialkali agent, nanosilica,...
In mountain tunnels, a series of advanced reinforcement measures are often employed to maintain the stability tunnel face, particularly in challenging geological conditions. However, there is lack design theories regarding support structure for uniquely shaped faces, necessitating further exploration. Based on limit equilibrium method, this paper presents derivation mechanical model analyzing excavation face considering shape changes and bolts. Additionally, theory horizontal glass fiber...
