The Most Common Laboratory Procedures for the Evaluation of EPB TBMs Excavated Material Ecotoxicity in Italy: A Review

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....

Zerovalent iron for the remediation of contaminated aquifers.

Nanoremediation technologies are based on the injection of reactive nanomaterials into the subsurface to promote in situ degradation of the pollutants. At present, it appears as a valid and very promising alternative to traditional and already established remediation technologies, such as Pump&Treat, In-Situ Chemical Oxidation (ISCO), air sparging and permeable reactive barriers. Due to their small size, nanoparticles (e.g. nanoscale zerovalent iron) presents a high reactivity and can be exploited to generate a reactive zone to treat a wide...

The soil abrasion test apparatus: a literature review

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...

Cerchar Abrasivity test in tunnelling: a modified version for evaluating the performance of conditioning agents as wear preventers

The Cerchar Abrasivity test is used for assessing the abrasion of rock due to its simplicity and fast execution and it is considered one of the main wear indexes in tunnelling. Despite in standard condition the test is performed on a dry surface of a rock sample, this study introduces the possibility to carry out the test on a conditioned surface. In details, this work compares the Cerchar Abrasivity...

A VEM application to geomechanical simulations for underground fluid storage

In this paper, we discuss how to describe the geomechanical behavior of geological formations used for underground fluid storage through the application of the Virtual Element Method (VEM) on conforming polyhedral meshes for the solution of stress-strain equilibrium equations. Under the assumption of small deformations, the solution algorithm for an Isotropic Linear Elastic (ILE) constitutive law coupled...
