PVA Fiber Reinforced Shotcrete for Rehabilitation and Preventative Maintenance of Aging Culverts
The goal of this project was to investigate the potential for using PVA (polyvinyl alcohol) fiber reinforced mortar for the rehabilitation and preventative maintenance of aging metal highway drainage culverts using a spray-on liner application approach. The interest and impetus for the investigation resulted from prior work of the investigators with county engineers that pointed towards the nee...

Polyamide Fiber Reinforced Shotcrete for Tunnel Application
This study intends to establish the mechanical properties of polyamide fiber reinforced shotcrete (PAFRS) in terms of compressive and flexural strengths, in accordance with ASTM C1609/C1609M-12. The mechanical properties identified the influence of polyamide fiber content on the PAFRS strength. This study evaluated the toughness of PAFRS and proposed additional toughness level criteria to bette...
متن کاملInfluence of the Constitutive Model for Shotcrete on the Predicted Structural Behavior of the Shotcrete Shell of a Deep Tunnel
The aim of the present paper is to investigate the influence of the constitutive model for shotcrete on the predicted displacements and stresses in shotcrete shells of deep tunnels. Previously proposed shotcrete models as well as a new extended damage plasticity model for shotcrete are evaluated in the context of 2D finite element simulations of the excavation of a stretch of a deep tunnel by m...
