A new computer modeling technology allows to more accurately predict the impact of earthworks on nearby buildings.

On Wednesday, February 24, it became known that an effective technology of geomechanical forecasting and design for construction in dense urban areas was developed at the Department of Mining and Underground Structures Construction of St. Petersburg Mining University.

Numerical three-dimensional models are used to find the regularities of stress and strain changes in the “soil-trench-building” system depending on the geometry of objects and their mutual location, taking into account the features of bearing and enclosing structures of pits, types of soil, and its state.

“Large cities and megalopolises face the problem of the lack of free space for the construction. We have to resort to compact construction, which bears the risk of damaging the buildings and structures around the construction site. The scarcity of free space also leads to the need for more active development of underground space. However, increasing the depth of pits during construction further aggravates the problem,” said the author of the development, a 3-year postgraduate student in the field of “Geomechanics” Vasily Komolov.

Based on the new forecasting technology, accurate recommendations for builders on the choice of the type of anchorage and parameters of the supporting and enclosing structures of pits can be made.

The results of the research of Mining University have been published in the journals indexed by the scientometric databases Scopus and Web of Science. The scientific project was supported by a grant from the Russian Foundation for Basic Research.

As a reminder, Samara State Technical University has created a test facility that recreates under laboratory conditions the physical parameters of rock deposits and determines their hardness, elasticity, plasticity, and other mechanical properties.
