"temperature controlled triaxial test"

Mechanical behaviour of clastic formations at shallow – medium depths which bear hydrocarbon reservoirs could exhibit an important non-linear influence of the strain on the formation stiffness during depletion. Particularly in the early reservoir production stage, characterized by high uncertainty and little ground movement data for back-analysis, reliable determination of formation stiffness at...


Harmonic Pulse Testing was introduced in the early 1970’s as a special case of pulse testing. It is characterized by a periodic variation of production/injection rate. Subsequent developments proved that it could provide the same information as a conventional well test (permeability and skin, heterogeneity) in addition to those given by a pulse test (areal connectivity within the reservoir) if proper...


The paper presents the results of an experimental campaign carried out at the Sasso Poiano mine, close to Varese, northern Italy. The area is near a historic site, inhabited villages and a well-known lake, so that the use of explosive is subject to severe restrictions imposed by Italian standards. The exploitation is therefore carried out by blasting with low specific charge (PF=50 g/m3) in order to obtain...


The rapid development of the mechanized tunneling in current decades has raised serious concerns about the environmental impact of large quantities of the muck. EPB-TBMs require the use of foaming agents for optimizing the soil conditioning. These agents could contain some chemicals (e.g., sodium lauryl ether sulfate – SLES) that are not included in the current legislation at the Italian or EU level....


Zandobbio Marble is a crystalline dolomite produced in an open pit quarry near Bergamo, Nord Italy. This ornamental stone was already used during the Roman age. For many years the quarry was inactive, until 2006 when it was re-opened. Local law on quarries requires the elaboration of an exploitation plan: its objective, and in general the objective of the environmental assessment, is to identify areas...


The paper provides an overview of the several scientific and technical issues and challenges to be addressed for underground storage of carbon dioxide, hydrogen and mixtures of hydrogen and natural gas. The experience gained on underground energy systems and materials is complemented by new competences to adequately respond to the new needs raised by transition from fossil fuels to renewables. The experimental...


The wear phenomenon plays a fundamental role in excavation work, as it directly affects
times and costs. While prediction models are available in the literature for rock applications,
a standardized procedure for predicting wear is not yet available for soils. In this
work, the Soil Abrasion Test Apparatus (SATA) is used to study the wear dependence from
the moisture content. 6 different types of soils were tested by varying the moisture content
and results were obtained in terms of weight loss...

One of the expected effects of global warming is the gradual melting of permafrost. Its melting will significantly impact soil material properties, potentially causing instability of infrastructures and triggering natural hazards.
The objective of this experimentation is to quantify the effect of thawing on the geomechanical strength of a reconstituted fine soil. More specifically, it is intended to qualify the initial frozen state and compare it to the state after thawing. This study was carried out in three steps. To begin, soil samples were...

CiteScore:
2020: 3.8
CiteScore measures the average citations received per peer-reviewed document published in this title.
CiteScore values are based on citation counts in a range of four years (e.g. 2016-2019) to peer-reviewed documents (articles, reviews, conference papers, data papers and book chapters) published in the same four calendar years, divided by the number of these documents in these same four years (e.g. 2016 —19).
Source Normalized Impact per Paper (SNIP):
2019: 1.307
SNIP measures contextual citation impact by weighting citations based on the total number of citations in a subject field.
SCImago Journal Rank (SJR)
2019: o.657
SJR is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and a qualitative measure of the journal's impact.
Journal Metrics: CiteScore: 1.0 , Source Normalized Impact per Paper (SNIP): 0.381 SCImago Journal Rank (SJR): 0.163
