On May 26-28, 2021, the Perm National Research Polytechnic University (Perm city , Russia) hosted the II All-Russian conference with international participation on "Deep foundations and geotechnical problems of territories". For the first time, the conference was held in a mixed ( hybrid) format: face-to-face and online. The broadcast of the conference will be available on YouTube.

The Perm National Research Polytechnic University, the Ministry of Education and Science of the Perm, the Russian Society for Soil Mechanics, Geotechnics and Foundation Engineering, the Russian Academy of Archi-tecture and Building Sciences, and the Siberian Geotechnics Association (Т-воСибГт-в) organized the conference.

One hundred thirty people attended the conference. The geography of the conference covers universities and research organizations in various regions of Russia, Kazakhstan, Azerbaijan, Uzbekistan, Italy, Germany, Turkey, France, Czech Republic, Estonia. More than 150 authors presented 79 reports at the conference, 12 poster presentations were presented. As a result of the conference, two collections of articles will be pub-lished. Оne of them will be indexed in the Scopus citation database, and the other in the RSCI. It is also planned to release a special thematic issue of the journal "Construction and Geotechnics", included in the list of the Higher Attestation Commission and the RSCI base, which will consist of selected reports of the conference.

During the conference, modern geotechnical technology for constructing foundations and foundations in various soil and climatic conditions, including in potentially dangerous areas, and modern methods of engi-neering surveys and testing of newly erected objects, were discussed. Practical experience of strengthening the foundations of existing buildings and structures was reported. New materials and technologies in road construction are presented. The results of experimental and theoretical research in geotechnics and foun-dation engineering, methods of modeling, and calculations of foundations and foundations are discussed.

The conference was held with the active participation of foreign professors, who shared the results of their research and exciting experience in the development of underground space in countries near and far abroad.

Students and undergraduates of the direction «Civil Engineering», graduate students and young scientists of PNRPU, representatives of design and construction organizations in Perm, attended the conference. At the conference, a scientific commission was created to evaluate the presented poster presentations.
