Permafrost scientists in Yamal continue monitoring capital construction projects

The monitoring system allows for tracking changes in permafrost and conducting necessary repairs in a timely manner.

Researchers from the Arctic Study Centre have begun the second phase of the pilot project, which involves setting up and implementing an automated geotechnical monitoring system for soil conditions under the foundations of capital construction projects in Salekhard. The Telegram channel 'Yamal-Arctic' reports this.

In the course of fieldwork, scientists will drill 12-mette deep permafrost-parameter wells and install thermometric equipment beneath 17 major buildings in the district capital.

Recall that during the first phase of the project, 23 major structures were equipped with a monitoring system, and 154 boreholes were drilled with partial soil sampling (core) for studying physical and mechanical properties. Data from all equipped wells is gathered on a data collection and visualisation portal and analysed by scientists from Yamal. Mathematical models are constructed based on laboratory soil studies and well thermometry, aiming to predict temperature fields at the foundation base.

'The pilot project is being carried out at eight locations. We are monitoring the behaviour of soils under the foundations of multi-story, heavily frequented buildings, as well as houses built in the 1980s and 1990s. The thickness of the permafrost was different back then,' Alexey Titovsky, the city's head, told Komsomolskaya Pravda.

According to him, there are future plans to modify urban planning standards and incorporate a monitoring system during the construction stage.
