Three-dimensional engineering-geological model of the soil massif: the case study of the base of a hydrotechnical building

Abstract

In the process of engineering and geological surveys, three-dimensional engineering-geological modeling makes it possible to perform a comprehensive assessment of the state of the territory for making sound-design decisions on the placement of construction sites and their structures. Secondly, a logical conclusion of a detailed study of engineering-geological and geotechnical conditions, which is implemented to use three-dimensional modeling, is a well-grounded design with a reasonable margin of safety, which causes a reduction in the total cost of the erected or reconstructed structure. Thirdly, in comparison with traditional engineering-geological two-dimensional models (cuts, maps, etc.), three-dimensional models give more information. This is especially important, when we think about the scale of the hydraulic structures. According to archival materials, it can be noted that there are many spatial geological heterogeneities in this territory, and the engineering-geological conditions turned out to be complex. Taking into account the advantages of three-dimensional modeling, the creation of a three-dimensional model of a dispersed soil massif is an actual task for solving complex engineering-geological problems. The article analyzes a three-dimensional engineering-geological model of the soil massif under a hydrotechnical building in the Moscow region, and then calculates its stress-strain state and the coefficient of stability of the sides of the ditch.
