Interpretation of an artificial ground freezing field trial at Fori Imperiali in Rome Open
This paper describes a field trial of artificial ground freezing (AGF) carried out in connection with the construction of Line C of Roma underground. AGF was one of the options considered for the temporary stabilisation of the ground durin…

Freezing-thawing response of sand-kaolin mixtures in oedometric conditions Open
The freezing and thawing cycles applied to soils can often be causes of irreversible instabilities, uplift, or subsidence. These phenomena can be both natural ( e.g . permafrost regions) or artificially induced ( e.g . artificial ground fr…

GEOLAB Project FROSPER: FROst heaving soils-Solar Panel foundations interaction in cold European Regions: an experimental study Open
The objective of the proposed project is to investigate the resilience of solar panels foundations in cold climates. The efficiency of solar panels is overall better in cold climates, when the direct sunlight is available, due to the lower…

Microstructure of Crushable Expanded Clay Aggregates Open
The images show two different and complementary views of a mixture of Light Expanded Clay Aggregate (LECA) particles with size ranging between 0.25–1.0 mm. The upper-left is a SEM image showing a projected view of the particles, while the …

Numerical study on the effects of groundwater table oscillation beneath the “Palazzaccio” courthouse in Rome Open
This work aims to evaluate the settlement induced by the river Tiber groundwater table oscillations. A representative section of the subsoil beneath the courthouse “Palazzaccio”, close to the river in the city centre of Rome, is analysed v…

Geotechnical and historical aspects on the collapse of the Tiber embankment walls in the centre of Roma (1870–1900) Open
This paper deals with the issues related to the construction of the Tiber’s embankment
\nwalls between years 1870–1926. The embankment walls (muraglioni) were designed by
\nRaffaele Canevari to mitigate the effects of the river inundation …

Some Notes on Granular Mixtures with Finite, Discrete Fractal Distribution Open
Why fractal distribution is so frequent? It is true that fractal dimension is always less than 3? Why fractal dimension of 2.5 to 2.9 seems to be steady-state or stable? Why the fractal distributions are the limit distributions of the degr…

A fractal analysis method to characterise rock joint morphology Open
Rock joints morphological characteristics strongly influence the shear strength dilatancy response of the discontinuity. Morphological features of rock joints are commonly identified with a roughness descriptor along standard 100 mm-length…

Packing density of bi-disperse mixtures under one-dimensional compression Open
This work aims to investigate the effect of fines in different type of bi-disperse grain size distributions in terms of minimum/maximum density, compressibility and crushing. The material adopted is the Light Expanded Clay Aggregate (LECA)…

Breakage mechanisms of highly porous particles in 1D compression revealed by X-ray tomography Open
Grain breakage affects a number of geotechnical engineering problems. In this research study, the breakage of an artificial, porous granular material (light-expanded clay aggregate (LECA)) has been studied in one-dimensional compression wi…

Contour fractal analysis of grains Open
\nFractal analysis has been shown to be useful in image processing to characterise the shape and the grey-scale complexity in different applications spanning from electronic to medical engineering (e.g. [1]). Fractal analysis consists of s…

Weibull Distribution to Describe Grading Evolution of Materials with Crushable Grains Open
This work presents a study on the evolution of the Grain Size Distribution (GSD) of an artificial granular material with crushable grains and its relation with the observed mechanical behaviour. The main aim of the work is to find a relati…
