Abstract
Erection of structures on soft soils is a difficult task. The cost of the foundation in such cases can be up to 30-35% of the cost of the entire structure. Therefore, an urgent task is the use of effective foundation structures. The use of reinforcing geosynthetic materials is one such method. The article describes the experience of using geosynthetic reinforcing materials in the construction of the foundation for steel cylindrical vertical tanks with a volume of 630 m3. The results of calculations of the settlement of tank foundations by the analytical method and the finite element method are presented. The obtained values of vertical displacements were compared with the results of geodesic measurements of the constructed reservoirs. The analysis of the results obtained showed good convergence of the calculation results by the analytical method with the actual measurements of the vertical displacements of the foundations. Also, the economic efficiency of using a foundation on a reinforced base was determined.
