A global overview of the technologies that can be applied for modern tunnelling construction taking into account the OS&H aspects is shortly presented in the paper.


The interaction between tunnels and underground water is a complex topic and it is of great relevance taking into account the environment, the protection of drinkable water and the interference with tunnel construction method. Due to the great importance of the topic, in the following are presented and discussed the most relevant technologies for water management in tunnelling with a specific attention...


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....


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 two-component backfilling system is the most frequently used method to fill the annular gap created during the shield machine advancement. This gap, due to the head overcut, the shield thickness and conicity and the tail brushes size should be filled continuously in order to avoid mainly surface displacement and linings movements. Nowadays this technology is the most chosen due to operative (both...


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...

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
