Rock strength properties of granitic rocks in Yosemite Valley, Yosemite National Park, California

Yosemite National Park, located in the central part of California’s Sierra Nevada mountains, is a glacially carved landscape filled with iconic rock formations such as Cathedral Peak, El Capitan, and Half Dome. Igneous rocks, consisting primarily of variat ...

Analysis of TBM tunnelling performance in faulted and highly fractured rocks

Erika Paltrinieri

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 ...

Review and Advances in Methodologies for Rockfall Hazard and Risk Assessment

Vincent Labiouse, Jacopo Maria Abbruzzese

This section reviews the current methodologies that are used for the assessment of the rockfall susceptibility, hazard and risk. Emphasis is given on quantitative methods although qualitative ones are also discussed. The different methodologies are present ...

Influence of the geometry of partially-spanning joints on mechanical properties of rock in uniaxial compression

Jian Zhao

As jointed rocks consist of joints embedded within intact rock blocks, their behavior depends on the behaviors of the joints and the intact rock blocks. In a jointed rock, there are two levels of heterogeneity within the jointed rocks due to the difference ...

Riprap Protection of Vertical-Wall and Spill-Through Bridge Abutments

Anton Schleiss, António Heleno Cardoso

Scour around bridge abutments frequently leads to the collapse of bridge superstructures. Consequently, scour countermeasures are usually designed and installed by river engineers, riprap matting being the most widespread solution. The associated design cr ...

Statistical Analysis of Mountain Permafrost Temperatures

Evelyn Zenklusen Mutter

The consequences of climate change are clearly visible in the Swiss Alps. In the past decades, increasing air temperatures have induced pronounced glacier retreat and permafrost thawing. Thawing permafrost in steep terrain is a potential natural hazard, as ...

Methods for predicting rockfall trajectories and runout zones

Vincent Labiouse

Rockfall hazard assessment without the use of rockfall trajectory and runout zone models is unthinkable in the 21st century. Such rockfall models have existed since the sixties, but nowadays an almost confusing palette of rockfall trajectory and runout zon ...

Challenges in achieving European-wide methodologies for rock fall hazard mapping

Vincent Labiouse, Jacopo Maria Abbruzzese

European-wide standard methodologies for rock fall hazard assessment and mapping would constitute a very important step towards more transparent and reproducible procedures used for these purposes, and would provide as well a higher uniformity in land use ...

Half-scale experimental study of rockfall impacts on sandy slopes

Vincent Labiouse, Barbara Heidenreich

In the framework of rockfall trajectory modelling, the bouncing phenomenon occurring when a rock block impacts with the slope surface is the most difficult to predict, owing to its complexity and its very limited understanding. To date, the rebound is comm ...

Rockfall protection as an integral task

Vincent Labiouse, Thomas Vogel

Among the different natural hazards, rockfall has an important place even though other natural hazards could affect more people or have greater consequences. The phenomenon may be further classified according to the size of the largest blocks and the total ...
