Hydraulic stimulation of pre-existing discontinuities in tight rocks

Federico Ciardo

Hydraulic stimulation is an engineering technique whose aim is to enhance the permeability of fractured rock masses at depths ranging from one to five kilometers. It consists in the injection of fluid at sufficiently high pressure in order to shear pre-exi ...

Advanced models for stress evaluation and safety assessment in steel-lined pressure tunnels

Anton Schleiss, Pedro Filipe De Almeida Manso, Alexandre Jean Pachoud

An accurate estimation of the stress in a steel liner is required for the design of steel-lined pressure shafts, both with regard to safety assessment of ageing steel-lined waterways of hydropower plants built in the 20th century, and for new projects whic ...

Turbulent planar wakes under pressure gradient conditions

Fernando Porté Agel, Sina Shamsoddin

Accurate prediction of the spatial evolution of turbulent wake flows under pressure gradient conditions is required in some engineering applications such as the design of high-lift devices and wind farms over topography. In this paper, we aim to develop an ...

Improved analytical solutions for the response of underground excavations in rock masses satisfying the generalized Hoek-Brown failure criterion

Vincent Labiouse

Analytical solutions for tunnel design are widely used in practical engineering, as they allow a quick analysis of design issues such as estimation of support requirement. In recent years, several papers analyzing the behavior of rock masses that obey the ...
