The paper is considered modelling the process elaboration of a pit for high-rise building in the case of dense urban area. The research is analyzed stress strain state of soil with retaning wall. The authors are developed various design solutions of the retainig wall to decrease of displacement of the nodals in soil finite element model. According the results, it has selected rational design solution of retaining wall.
Keywords: dense urban areas, retaining wall, finite element method, stress-strain state, soil massif
The article is devoted to the development of a methodology for preliminary assessment of the geotechnical situation of the site for the reconstruction of construction of unique buildings and structures and its explanation. Was the method of determining the geotechnical category, the complexity of a new building and highlighted the main aspects of the stages of the methodology.
Keywords: geotechnical situation, unique buildings, investment risks, risk category, category of responsibility of an object category of technical condition of foundations
In this article the territory of the city of Rostov-on-Don is considered and engineering-geological conditions for the purpose of construction of buildings and constructions on a monolithic base plate of small laying are analysed. The schedule of dependence of the limit module of deformation on pressure under a base sole is constructed. The analysis of engineering-geological conditions in the city of Rostov-on-Don is made, and also the map and the chart of distribution of the average module of deformation in his territory are made.
Keywords: the average module of deformation, extreme draft of a subfoundation, pressure under a base sole, a monolithic base plate
The paper proposes to perform quality control of the production work on the consolidation of soil foundation with the use of the method. Application of geo-radiolocation sensing allows to specify and complement the results of engineering and geological surveys, as well as capture the changes taking place in the grounds of foundations after work on fixing them. This will provide a comprehensive picture of the grouting in the underlying foundation of the building and provide a reliable and simple quality control work.
