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
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.
Method Of Calendar Planning Of Construction Of The Complex At The Early Stage Of Design, M Mirakhmedov, M. Rasulmukhamedov, L.S. Yusupova
Method Of Calendar Planning Of Construction Of The Complex At The Early Stage Of Design, M Mirakhmedov, M. Rasulmukhamedov, L.S. Yusupova
Journal of Tashkent Institute of Railway Engineers
The construction schedule developed in the construction organization project does not meet the requirements of the reserve for construction, is not based on the choice of construction and technological schemes and the method of construction organization, therefore, it is not sufficiently reliable, the evidence base stored in the project archive is not confirmed by calculations and Therefore, it cannot be subjected to reliable examination. To eliminate this drawback, a technique is proposed that takes into account the lack of information. The methodology is based on the graphanalytic model of the flow organization of the construction of the complex, which allows …
To The Conclusion Of The Variational Equation Of Motion Of Shell Structures Supported By Frames And Stringers, Farkhod Erkinovich Abdukadirov
To The Conclusion Of The Variational Equation Of Motion Of Shell Structures Supported By Frames And Stringers, Farkhod Erkinovich Abdukadirov
Journal of Tashkent Institute of Railway Engineers
In this article is given the construction of the variational equation of motion of the shell structure supported by frames and stringers. Using the Hamilton - Ostrogradsky variational principle, systems of differential equations of motion of shell elements are obtained.
Application Of Modern, Effective Materials In Rail Road Reinforced Bridge Elements, U.Z. Shermuxamedov, F.Z. Zokirov
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
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
Features Of Designs Of Nanosenses For The Oil Industry, A.E. Vorobev, Zhang Lianzi
Features Of Designs Of Nanosenses For The Oil Industry, A.E. Vorobev, Zhang Lianzi
Gorniy vestnik Uzbekistana
Development of design features of nanosensors for oil branch is shown. It is established that in modern nanosensors usually influence formation of a working signal as environment qualitative quantitative indices (values of temperature, pressure, speed of migration of fluids, contents of chemical elements, sizes рН, etc.) and the nature (predetermining properties), structure and extent (the geometrical sizes) of nanoparticles of sensitive elements which the studied environment influences, forming as a result this working signal. The basic design of nanosensors and the mechanism of their work is described. Distribution of nanosensors on classes depending on the principles and mechanisms of action …
