Current State And Prospects Of Construction Of High-Speed Railway Overpasses In Seismic Conditions Of The Republic Of Uzbekistan, Ulugbek Zabixullayevich Shermuxamedov, Saidxon Salixanovich Salixanov Jun 2020

Current State And Prospects Of Construction Of High-Speed Railway Overpasses In Seismic Conditions Of The Republic Of Uzbekistan, Ulugbek Zabixullayevich Shermuxamedov, Saidxon Salixanovich Salixanov

Journal of Tashkent Institute of Railway Engineers

The article deals with the issues of seismic stability of high-speed railway overpasses in the Republic of Uzbekistan, taking into account the experience of their design and construction in developed foreign countries. A review of technical solutions to ensure the seismic stability of overpasses and bridges located on high-speed and high-speed Railways in the world and in the Republic of Uzbekistan. Features of ensuring seismic stability of bridges and overpasses on high-speed lines are given.


State And Prospects Of Production And Operation Of Synthetic Woven Belts (Table) For Load-Handling Devices (Hd) In The Republic Of Uzbekistan, Ibrohim Numanovich Abdullaev, Zhamoldin Dzhalalovich Akhmedov, Bakhodir Kushakovich Rakhmanov, Ruzikhon Toyirzhanovna Zhurabaeva May 2020

Journal of Tashkent Institute of Railway Engineers

In the world, the use of synthetic woven tapes (SWT) is increasing in various areas of life, including in construction. In particular, thanks to the development of production of high-strength synthetic fibers in such developed countries as Russia, USA, Germany, progress has been made in the creation and manufacture of heavy-duty lifting slings from STL, and on this basis to improve ergonomics and safety of installers, the safety of transported goods, the reduction of labor input and material on the load capacity.


Application Of Modern, Effective Materials In Rail Road Reinforced Bridge Elements, U.Z. Shermuxamedov, F.Z. Zokirov Nov 2019

Application Of Modern, Effective Materials In Rail Road Reinforced Bridge Elements, U.Z. Shermuxamedov, F.Z. Zokirov

Journal of Tashkent Institute of Railway Engineers

The article is about reducing the construction costs of railroad bridges and the effective use modern building materials. The article compares the technical characteristics of composite fittings and metal fittings and their proportionality. Indeed, recourse saving of metal and composite fittings, as well as factors of localization of construction is compared


Method Of Calculation Of Self-Stressed Concrete Slabs Supported Along The Contour, S.S. Salixanov Nov 2019

Method Of Calculation Of Self-Stressed Concrete Slabs Supported Along The Contour, S.S. Salixanov

Journal of Tashkent Institute of Railway Engineers

The paper presents the developed method for calculating the contour-supported slab of self-stressed concrete. Reinforced concrete slab on the tension cement replaces the traditional construction of the bridge. In this article, in order to exclude reinforcement, the problem of determining the stress-strain state of self-stressed concrete slabs supported along the contour is considered. The values of stresses in the upper and lower faces of the concrete slab, as well as the bending moment in the middle section of the slab


Construction Features Of Transport Tunnels In The Mountain Areas Of Uzbekistan, M.Х. Miralimov, Sh.U. Normurodov Nov 2019

Construction Features Of Transport Tunnels In The Mountain Areas Of Uzbekistan, M.Х. Miralimov, Sh.U. Normurodov

Journal of Tashkent Institute of Railway Engineers

The paper provides information about the transport tunnel 19,2 km long which was recently completed on new electrified railway line “Angren-Pap” in the mountain area of Uzbekistan. It is noted that the most actual for transport tunnels is account of seismic activity of geological environment in the process of design, construction and maintenance. There are given the effects of earthquakes on underground structures and regularities of displacement and stress distribution in the tunnel linings under seismic impacts. The accumulated experience of earthquake-resistant construction in Uzbekistan shows the need to consider several design schemes for the interaction of tunnels in the …
