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 ...
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 ...
Energy piles are heat capacity systems that have been increasingly exploited to provide both supplies of energy and structural support to civil structures. The energy and geotechnical behaviours of such foundations, which are governed by their response to ...
The thesis focuses on the study of the performance of TBMs in highly jointed and faulted rocks. Despite the great production rates recorded in favourable ground conditions, the TBM advance can be significantly slowed down in limiting geological situations ...
In recent years, substantial advances have been made in understanding the coupling between chemical and biological processes and mechanical and hydraulic behaviours in soils and rocks. At the same time, experimentation and modelling capabilities have progr ...
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 ...
The lack of reliable methods for evaluation of soil abrasivity and revealing the effects of different parameters on wear rate are nowadays considered as a deficiency in geotechnical investigation during feasibility study, design and construction phases of ...
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 many fields of geotechnical engineering, the modelling of interfaces requires special numerical tools. This paper presents the formulation of a 3D fully coupled hydro-mechanical finite element of interface. The element belongs to the zero-thickness fami ...
Despite the potential excellent performance of TBMs in favourable ground conditions, the presence of fault zones or heavily jointed rocks represent important geological hazards encountered during tunnel excavation. The effects of these challenging environm ...
