Assessment of the Safety Factor Evolution of the Shotcrete Lining for Different Curing Ages

Oreste P.; Spagnoli G.; Luna Ramos C.A.; Hedayat A. (Springer International Publishing, 2019)

The behavior of the shotcrete linings during the tunnel construction is complex due to the variability of its mechanical characteristics during the curing time. After the installation of the support structure, the lining ...
Evaluation of the safety factors of shotcrete linings during the creep stage

Oreste P.; Spagnoli G.; Ramos C.A.L. (ICE Publishing, 2020)

Sprayed concrete linings (SCLs) used in tunnels generally develop secondary deformations over time, even in the presence of constant stress levels within the lining. These deformations influence the loading process on the ...
The Elastic Modulus Variation During the Shotcrete Curing Jointly Investigated by the Convergence-Confinement and the Hyperstatic Reaction Methods

Oreste P.; Spagnoli G.; Luna Ramos C.A. (Springer International Publishing, 2019)

Induced stresses in sprayed concrete (or shotcrete) are quite complex to evaluate and depend on many factors such as the size and depth of the tunnel, the geomechanical characteristics of the surrounding ground in which ...
