Advanced Underground Construction Technologies

Dear Colleagues,

Nowadays, underground space has become a hot point in urban development combined with surface buildings. However, give recent development in urban-intensive districts, traditional construction technologies cannot satisfy new requirement trends. Difficult engineering geological conditions, such as mixed layers, multi-confined aquifers, large deformation in soft surrounding rock, high temperatures, high water pressure, high stress, an erosion environment, water inrush, etc., together with difficult environment conditions, such as nearby buildings, base, piles, bypass tunnels or underground structures, pipes, and protected buildings, necessitate the use advanced underground construction technologies. Recently, lots of advanced underground construction technologies have been developed quickly and widely used. A technology revolution empowered by digitalization, AI, and advanced manufacturing industry might lead to the development of high-efficiency underground construction technology for difficult geological and environment conditions. Significant developments in underground construction technology should be summarized in this Special Issue, which focuses on advanced underground construction technologies such as vertical shield machines (VSMs), the actively controlled precast caisson sinking method (APM), TRD, RJP, the tube curtain method, rectangular shield tunneling, dual-mode TMBs, steel diaphragm walls, intelligent drilling and the blasting method, nonexcavation technology, groundwater control technology, low-carbon environmental protection technology, biological grouting technology, digital construction technology, etc. Studies of the theory, product, application, and case history regarding advanced underground construction technologies are all welcome. Professors, equipment manufacturers, industry businesspeople, and technical engineers are all encouraged to submit their studies for inclusion in this Special Issue. It is expected that these advanced underground construction technologies will be summarizable and applicable in time.

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.
