Design aspects of segmental tunnel lining in difficult rock conditions

Autor: A Poli, G Carrieri, R R Osgoui, G Quaglio

Publikováno v: IOP Conference Series: Earth and Environmental Science. 833:012073

Despite plenty of research studies in design of segmental tunnel lining, there have still been serious concerns in damage mechanism of segmental lining in weak rock masses. With significant increasing of mechanized tunnelling practically in all kind

An empirical method for design of grouted bolts in rock tunnels based on the Geological Strength Index (GSI)

Autor: Erdal Ünal, Reza R. Osgoui

Publikováno v: Engineering Geology. 107:154-166

The procedure presented in this paper has been developed for the design of grouted rock bolts in rock tunnels during preliminary design stage. The proposed approach provides a step-by-step procedure to set up a series of practical guidelines for opti

Elasto-plastic analytical model for the design of grouted bolts in a Hoek-Brown medium

Autor: Pierpaolo Oreste, Reza. R. Osgoui

Publikováno v: International Journal for Numerical and Analytical Methods in Geomechanics. 34:1651-1686

This paper presents an elasto-plastic analytical solution of an axi-symmetrical problem for a circular tunnel reinforced by grouted bolts. Considered as the improved model of Indraratna and Kaiser (Int. J. Rock. Mech. Min. Sci. Geomech. Abstr. 1990;
