摘要：

In order to quantitatively clarify the effects of steel fiber reinforced high-strength shotcrete (SFRS) applied to a squeezing tunnel, a non-linear numerical analysis is carried out, in which the stress-strain-time constitutive relationships of SFRS and the time-dependent movement of the ground surrounding the tunnel are taken into account. Through a comparison of field measurement and analytical results, it is recognized that SFRS can be applied as a reasonable primary lining for tunnels excavated in grounds with severe geological conditions. In particular, high strength during the early stages of the execution and ductility after its peak strength both contribute to the safe construction of squeezing tunnels.
