Text en actes de congrés
Accés restringit per política de l'editorialThe aim of this work is to deepen the knowledge of the numerical simulation used in the prediction of building dam age produced by tunnel ling subsidence. This paper analyzes the structural response of a one-storey building ... -
A coupled fluid FEM-DEM technique for predicting blasting operations in tunnels
(2018-12)
Article
Accés obertWe present recent developments in the coupling of the finite element method (FEM) and the discrete element method (DEM) for the analysis of rock blasting operations in tunnels. The coupled FEM-DEM technique has been proven ... -
A methodology for analysing the drainage system in excavations between sheet pile walls
(2009-10)
Comunicació de congrés
Accés obertThe development of an underground station below the water table requires rigorous and careful planning. As such an in depth knowledge of the station construction designs and the related hydraulic behavior are required in ... -

A plastic-damage approach to the excavation response of a circular opening in weak rock
(2022-08)
Article
Accés restringit per política de l'editorialDuring opening construction, the accumulated wall displacement and the developing excavation damaged zone are the results of stress redistribution and inelastic behavior induced by both the microcracking damage and the ... -
A review of expansive phenomena in Wagenburg North Tunnel
(2009-12-31)
Article
Accés obertThe paper deals on tunnelling and swelling in anhydritic-gypsiferous claystones. The geology of the Gipskeuper in Baden-Württemberg (Germany) and the phenomenology of expansions in Wagenburg North tunnel are described. ... -
A submersible drill rig for coring soils and rocks
(2012)
Text en actes de congrés
Accés restringit per política de l'editorialThe paper describes the design and initial field-testing of a remotely operated submersible drill rig able to obtain continuous cores of soil and/or rock up to 6 m long. The rig mast angle is hydraulically actuated covering ... -
Advances in the development of the discrete element method for excavation processes
(Centre Internacional de Mètodes Numèrics en Enginyeria (CIMNE), 2012)
Llibre
Accés obertThis work presents new developments of the discrete element method improving e ciency and accuracy of modelling of rock-like materials, especially in excavation processes. -
Advances in the Discrete Element Method for drilling mechanics problems
(2013)
Text en actes de congrés
Accés restringit per política de l'editorialWe present recent developments in the Discrete Element method (DEM) for analysis of drilling mechanics problems typical in the oil and gas industry. A new local DEM constitutive model able to predict the non-linear behavior ... -
Advances in the modelling of excavation and cutting tool wear with the particle finite element method
(Aedificatio, 2013)
Text en actes de congrés
Accés restringit per política de l'editorialThis work presents the new advances on the Particle Finite Element Method (PFEM) for the modeling of excavation processes and the wear of the cutting tools. In the PFEM [3, 9, 6], the continuum solid domains are defined ... -
An underground excavation in Barcelona and its interaction with existing structures
(Taylor & Francis Group, 2021)
Capítol de llibre
Accés restringit per política de l'editorialThe construction process for the enlargement of an underground railway station in Barcelona required an additional tunnel excavation below existing structures. The paper presents the case study, describing the details of ... -
An undrained upper bound solution for the face stability of tunnels reinforced by micropiles
