Present Status, Technology and Materials in Tunnelling and Underground Engineering

Dear Colleagues,

This Special Issue aims to define the state of the art regarding the new wave of modern technologies and methods for tunnel construction. The role of underground infrastructures is significant in the sustainable and resilient development of urban areas, but this sudden expansion has created more challenging operating conditions. In this context, the rapid growth of new technologies has facilitated the construction and operation of tunnels; on one hand, the use of automation and more advanced systems reduces risks during the construction phase, and on the other hand, innovative technologies and materials ensure excavation feasibility, even under environmental restrictions. Furthermore, new technologies are also expected to play a crucial role in organising more efficient maintenance campaigns to reduce traffic disruptions.

We welcome papers on topics including, but not limited to:

• Innovations in mechanised and conventional tunnel excavations;
• New technologies and materials in mechanised tunnelling (soil conditioning and backfilling);
• The application of AI in tunnelling excavation;
• Automation in the construction and operation of underground structures;
• The use of new technologies for reducing excavation risk;
• The use of new technologies for the maintenance of existing tunnels in operation.

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. 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.
