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 کاملModelling Tunnel Performance in Expansive Gypsum Claystone
ABSTRACT: Extreme swelling pressures (in excess of 5 MPa) were measured against the invert of a tunnel excavated by drill and blast method in a hard claystone containing variable proportions of anhydrite and gypsum dispersed in the clay matrix. When the invert was not present, floor heave reached displacements in excess of 60 cm in some cross sections. Displacements and pressures developed at a...
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...
متن کاملInfluence of the Tunnel Shape on Shotcrete Lining Stresses
Tunnel excavation is frequently carried out in rock masses by the drill and blast method and the final shape of the tunnel boundary can be irregular due to overbreaks. In order to investigate the effects of overbreaks a study of the effect of tunnel boundary irregularity has been carried out. This is done developing a computational tool able to take into account fuzzy variables (i.e., thickness...
متن کاملTunnel boring machine positioning automation in tunnel construction
Purpose Tunnel construction using a tunnel boring machine (TBM) entails precise machine positioning and guidance in the underground space. In contrast to traditional laser-based machine guidance solutions, the proposed research aims to develop an automation alternative to facilitate TBMguidance and as-built tunnel alignment survey during tunnelling operations. Method A fully automated system is...
