Strength and Deformability Anisotropy of Fiber-Reinforced Shotcrete
The importance of shotcrete anisotropy has not been properly taken into consideration for the design of underground works. The spraying process creates strata, perpendicular to the direction of spraying, which induce anisotropy on both strength and deformability. In addition to that, properties are usually measured by testing cores obtained perpendicular to the stratification, whereas the major principal stresses are parallel to that direction. This paper presents the results of uniaxial compression tests carried out on specimens cored from a fiber-reinforced wet mix shotcrete used for final lining of the Morro Doce Tunnel, one of the tunnels constructed for the West section of the São Paulo Ring Road. Strength and elastic constants were determined on specimens oriented both parallel and perpendicular to the strata. Differences in the post-peak behavior were encountered, indicating different degrees of ductility.
