Currently, there are many software systems and environments that allow you to simulate and perform fairly complex and voluminous calculations associated with dynamic effects on structural elements of overpasses. The aim of the article is to make an analysis of a reinforced concrete railway overpass as a whole and its elements separately. The article presents the calculated and experimental data of the forms and frequencies of natural vibrations of reinforced concrete railway overpasses under constant loads and the rolling stock off the span. As a result of the analysis of the tests, it was determined that the effect of the rolling stock passing through the reinforced concrete beam spans of 16.5 m and 23.6 m appears with frequency perturbations that are in the range f = 4.41 ÷ 9.52 Hz. These studies can be further used in the design of artificial structures, as well as to identify defects in structural elements of railway bridges.

Adding of a multi-walled carbon nanotubes (MWCNTs) to epoxy resin has shown promising results in improving fracture toughness in bulk epoxy and carbon fiber-reinforced epoxy composites (CFRP). using a hand layup proceeding followed by the so called vacuum bagging process method, carbon fiber-reinforced polymer multi-wall carbon nanotubes (MWCNTs) was added to an epoxy resin with a weight percentage mixing of 1% wt., 1.25% wt., and 1.5 % wt. MWCNTs. Furthermore, the specimen underwent analysis via Fourier-Transform Infrared (FTIR) spectroscopy, and X-ray Diffraction (XRD) spectroscopy, the composites were subjected to a microscopic examination using a Scanning Electron Microscope (SEM). FTIR and XRD verified the folding and unfolding of the polymer, in addition, the mechanical properties including tensile strength, bending stress, and impact behavior were investigated as well as the hardness test. The obtained results showed a significant improvement of about (40 %) in tensile strength, (53 %) in bending stress at 1 % wt. MWCNTs, and (70 %) percentage increment in the strength of Impact at 1.25 % wt. MWCNTs. And the gained hardness was about 40.5 HV which were compared with a reference substance named Carbon Fiber (CF) without any addition of nano materials. Carbon nanotubes have demonstrated their potential to enhance the mechanical properties of fiber-reinforced polymers, so this investigative study employs comprehensive characterization techniques, and demonstrates significant improvements in mechanical properties for the modified polymeric composite materials supported with nano materials.

“…It was previously believed that polymer flooding was limited to use only in fields with light oil or with medium viscous oil, and thermal oil recovery methods were strictly applied in fields characterized by high viscosity oil (Babaytsev et al, 2017;Kuznetsova and Rabinskiy, 2019;Formalev et al, 2017;Gendler et al, 2019). However, recently in world practice, this provision is no longer observed in connection with the successful use of polymer flooding for highviscosity oil, where thermal methods do not seem feasible (Radyuk et al, 2019;Samarin et al, 2019).…”

One of the chemical methods of stimulating the reservoir to increase the efficiency of the oil field development process is polymer flooding. This article conducted a feasibility study of the effectiveness of the application of polymer flooding technology in one field in Western Kazakhstan. This field is characterized by high viscosity of reservoir oil, water cut, and dynamic heterogeneity of the reservoir. World experience in the application of polymer flooding in analogous fields shows high technological efficiency. Presented results of the analysis of the experience of applying technology in analogous fields, physicochemical studies of polymers, filtration studies on bulk models, hydrodynamic modeling of polymer flooding and the expected cost-effectiveness of introducing the technology, as applied to the conditions of the Karazhanbas oil field with high viscosity of reservoir oil. The analysis based on the experience of applying polymer flooding in high-viscosity oil fields, laboratory studies and estimated calculations of the expected production in the sector geological and hydrodynamic model shows a decrease in water cut, an increase in oil production, and an increase in current and final oil recovery.
