Autor: Emad Jahangir, Laura Blanco-Martín, Faouzi Hadj-Hassen, Michel Tijani

Publikováno v: Journal of Rock Mechanics and Geotechnical Engineering, Vol 13, Iss 4, Pp 811-819 (2021)

This paper proposes a new interface constitutive model for fully grouted rock-bolts and cable-bolts based on pull-out test results. A database was created combining published experimental data with in-house tests. By means of a comprehensive framewor

Tunnelling-induced surface settlement: on the choice of soil constitutive model

Autor: Ahmed Rouabhi, Sara Rachdi, Michel Tijani, Emad Jahangir

Publikováno v: European Journal of Environmental and Civil Engineering
European Journal of Environmental and Civil Engineering, Taylor & Francis, 2019, ⟨10.1080/19648189.2019.1639078⟩

International audience; Increasing tunnel excavations in dense urban areas faces the issue of accurately predicting tunnelling-induced surface settlement. The quality of those predictions closely depends on the choice of soil constitutive model. In t

An approach to model the mechanical behavior of transversely isotropic materials

Autor: Sylvie Granet, Ahmed Rouabhi, Mohamed Ali Mahjoub, Michel Tijani

Publikováno v: International Journal for Numerical and Analytical Methods in Geomechanics. 40:942-961

Summary The present work proposes an approach to adapt existing isotropic models to transversely isotropic materials. The main idea is to introduce equivalence relations between the real material and a fictitious isotropic one on which one can take a
