Failure and Deformation Behavior of Underground Geo-Structures: Advances in Geomechanics

Dear Colleagues,

Underground engineering has rapidly grown to meet the increasing societal needs and is moving towards challenging innovations.

Mining and energy geomechanics is presently facing complex underground conditions related to uncertainties in the determination of rock strength and deformability, in situ stresses, and pore fluid pressure coupled with problems induced by high stresses at large depths. Furthermore, the processes related to CO₂ sequestration and storage require specific analysis of the rock geomechanical response induced by the geochemical reactions.

On the other hand, the need for transport efficiency in urban areas is presently addressing the construction of tunnels at narrow distances and the underground space use requires an appropriate analysis of rock damage for safety during service.

Civil, nuclear, and hydropower underground spaces, mines, wellbores for hydrocarbon production and gas storage, and geothermal energy extraction are subject to adverse factors during construction and service. Unexpected rock failures and excessive deformations can reduce or inhibit the engineering function of these works. The mitigation of these events includes post-disaster analysis in order to refocus the efforts on measures to reduce preventable failures and collapses, coupled with experimental approaches, analytical and numerical analysis, and data-driven techniques.

This Special Issue aims at constructing a channel for sharing knowledge on recent advances in Geomechanics to mitigate adverse events and to address challenges and potential solutions for the sustainable and resilient construction of underground geo-structures.

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 250 words) can be sent to the Editorial Office for assessment.

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-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences 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 2400 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.
