Analysis of Temporal-Spatial Effect for Tunnel Construction in the Fault-Rupture Zone
Based on the existing research results, this paper proposes a temporal-spatial relational expression of displacements of tunnel perimeter during tunnel excavation. Taking Guanjiao tunnel as example, using the expression, temporal-spatial effect for Guanjiao tunnel in the fault-rupture zone are analyzed and studied. Comparison of theoretical solutions with measurements has proved that temporal-spatial effect for soft rock tunnel can be reflected by the expression and these results provide reasonable proposal for the optimum time to construct the secondary lining.( the constructing time of secondary lining) and reserved deformation.
