The safety of circumferential yielding lining is influenced significantly by the shotcrete
hardening property. However, presently, negligible research attention has been paid to this …

Tunneling stoppage often occurs during tunnel construction, especially in weak and
rheological ground. The discontinuous excavation caused by the stoppage usually has a …

This paper presents a novel hybrid model designed for predicting mountain tunnel
deformation during construction, incorporating both temporal and static factors. Utilizing a …

For tunnelling in a deep soft rock mass, rock rheology and the advancing process
significantly affect the induced pressures on the support system and the long-term safety of …

Rock load on lining structures increases over time for tunnels buried in rheological rock, and
in addition deterioration of primary lining is common due to its structural characteristics and …

The predicted performance of a geotechnical system may deviate from the in situ
observation due to the uncertainties in the input geotechnical parameters, solution model …

For tunneling in a deep, soft rock mass, rock deformation and lining pressure, which are time-
dependent behaviors, are mainly affected by rock rheology and longitudinal excavation …

The shotcrete stiffness varies over time in the hardening period, which complexes the
interaction between support structures and rheological rock. This study presents an …
