Special Issue Information
Dear Colleagues,
The safety and stability of deep underground projects have become a challenging topic of increasing interest. With the gradual exhaustion of shallow mineral resources and energy, the depth of further extraction and exploitation continues to increase. Meanwhile, many deep transit and water conveyance tunnels are planned or under construction in mountain areas. In recent years, advanced technologies for laboratory testing, geotechnical modeling, and field monitoring have been deployed to characterize the physical properties and mechanical resistances of geomaterials in deep underground engineering. By assessing the inherent properties of geomaterials that determine their behaviors under various conditions, the results will significantly benefit the design, construction, and management of support systems, excavation methods, and safety measures to ensure the successful completion of underground projects while mitigating geological and geotechnical challenges.
This Special Issue aims to identify cutting-edge research and recent advancements in the theories, technologies, and numerical methods in terms of the physical characterization and mechanical resistance of deep geomaterials. We welcome the submission of research papers as well as review articles. The focal points include, but are not limited to, the following themes:
- Geological mapping and surveys to identify rock types, faults, and fractures.
- Characterization of mineralogical composition, grain size, and pore structure.
- Development and implementation of advanced monitoring systems to measure stress, strain, and deformation in underground structures.
- Computational geomechanics for simulating rock and soil deformation.
- Coupled thermal-hydro-mechanical modeling.
- Investigation of the behavior of fractured and jointed rock masses.
- Geomaterials behave under extreme pressure and temperature conditions encountered at great depths.
- Probabilistic risk assessment for underground structures by considering uncertainties in material properties
- Research on environmentally friendly and sustainable construction materials and techniques for underground engineering.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
