Viscoelastic properties of geosynthetic materials
Nowadays, geosynthetics are finding new applications in civil engineering. At the same time, the actual task is to evaluate and predict their mechanical properties for a long time. Taking into account the viscoelastic nature of synthetic polymers, of which the huge geosynthetics are manufactured, this article discusses options for defining and predicting their viscoelastic properties. The analysis shows the advantages and disadvantages of various methods of investigation the creep of geosynthetics, including direct measurement of creep, timetemperature superposition, step isothermal method.

Work of special rod system depending on its geometry
In this article it was analyzed how does structural system for long-span roofs behave under the loads in order to determine the rationality of using such constructive scheme and its geometric parameters on example of Polytechnicheskaya metro station in Saint-Petersburg. In the course of the work, the finite-element model of the coating was calculated. Then its height was varied using seven different types of computer models. Calculations were done in SCAD 21 software complex. A technical and economic comparison of different covering options was carried out to determine the height of the structure, which leads to significant decrease of internal forces to reduce the costs. It was proved that the applied approach is efficient and economical.

Effectiveness of jet grouting method for soil base strengthening
This paper examines the effectiveness of technology using jet grouting. This technology is commonly used to strengthening the weak soil bases of buildings in dense urban areas. The paper presents the calculation research methodology and results of the effectiveness of this method on the example of shopping malls in St. Petersburg. Frame type buildings, having numerous cracks in the floor slabs, are considered. Bearing elements of these buildings are the columns, based on the individual pile foundations. Concrete floor slabs are supported by soil base. In the calculations, the soil base was modeled by volumetric finite elements and concrete floor slabs – by plate finite elements. Cement-soil elements (pillars) were modeled also by volumetric finite elements with different deformation modulus. It can be concluded from the calculation results that the above technique is effective in the presence of the weak soil layers and the increase in the modulus of cement-soil elements more than 400 MPa is impractical.
