Anisotropic fabric and volumetric response to suction changes represent two main features of shales, which are involved in several engineering applications. However, a comprehensive understanding of the interaction between these two aspects is still missin ...
Adopting effective maintenance strategies for transportation infrastructures requires good prediction of their long-term behaviour. For planning interventions without affecting the entire network’s capacity, tunnels in particular require a good overview of ...
Traffic congestion and ground space scarcity are increasing the need to find more space in the urban underground. The demand-driven "top-down" planning of Urban Underground Space (UUS) is common worldwide. As natural resource, the endowments of UUS are dif ...
Calcareous fly ashes are high-potential reactive supplementary cementitious materials, which present an interesting alternative to slowly reacting siliceous fly ashes and to slags, which availability is more and more limited. Themain factor against an accu ...
When we have to valorise the geological information for land planning or engineering applications, it is difficult to integrate the large complexity of the maps of the Swiss Geological Atlas at the scale of 1:25'000. The heterogeneity of the legends betwee ...
This study focuses on the derivation of a semi-analytical approach for the evaluation of surface uplift and caprock deflection induced by underground injection of CO2. The adopted methodology includes the development of a mathematical model that incorporat ...
Laser ultrasound (LU) data acquired on cylindrical core samples effectively probe the physical properties of geologic materials. Although most LU analyses focus on estimating and inverting traveltimes of direct arrivals, it is important to recognize that L ...
In 1879, then 23-year-old Maurice Koechlin became the lead structural engineer of Gustave Eiffel’s construction company founded 13 years before. Together, they pushed the boundaries of steel and iron structural design. They were responsible for the design ...
Using a spectral resolution of the elastodynamic boundary integral equations, this poster is presenting the effect of tougher heterogeneities along a planar fracture plane. A centered crack propagating along a 1-D heterogeneous interface under mixed-mode l ...
Opalinus Clay (OPA) is the host rock being proposed in Switzerland for disposal of high-level radioactive waste. The stability of fault zones within this formation is a key issue to ensure long-term performance of the repository. To understand the friction ...
