Determination Of The Carrying Capability Of The Basis Of The Support Of A Contact Network Of The Railways And Vertical Force, Acting On The Base, K.S. Lesov, A.Kh. Mavlyanov, U.E. Ergashev

Journal of Tashkent Institute of Railway Engineers

The variant workings and calculations are executed on fixing of supports of contact trackage. Structural-technical decisions are Given on building of supports of contact network on earthen linen from sandy soils.


Model Of Search For The Placement Of Warehouses Of Tarnet-And-String Cargo Depending On The Cargo, Avaz Mirsultanovich Merganov Dec 2018

Model Of Search For The Placement Of Warehouses Of Tarnet-And-String Cargo Depending On The Cargo, Avaz Mirsultanovich Merganov

Journal of Tashkent Institute of Railway Engineers

To determine the feasibility of warehouses for packaged goods, it is necessary to understand the main volumes of cargo traffic, as well as to determine the optimal placement of these objects. These questions are developed and solved in this study


The Principles Of Calculation Of Preliminary-Stressed Reinforced Concrete Elements Of A Tripping Structure Under Dispersed Arming, Ch.S. Raupov, E.T. Yahshiyev, A.B. Karimova Dec 2018

The Principles Of Calculation Of Preliminary-Stressed Reinforced Concrete Elements Of A Tripping Structure Under Dispersed Arming, Ch.S. Raupov, E.T. Yahshiyev, A.B. Karimova

Journal of Tashkent Institute of Railway Engineers

It is known that the basic principle of the use of reinforcement in the cross section of building structures is associated with ensuring their strength under the action of bending, tensile loads and impacts and the need to reinforce concrete elements that do not have sufficient structural strength for tension and bending. Depending on the purpose and features of the building structures, there are different types of reinforcement and ways to strengthen the elements.

Ways Of Rational Enhancements Of Passage And Transportable Ability On Railways Jsc "Uty", S.K. Xudayberganov, A.A. Svetashev, Sh.Sh. Kayumov Dec 2018

Ways Of Rational Enhancements Of Passage And Transportable Ability On Railways Jsc "Uty", S.K. Xudayberganov, A.A. Svetashev, Sh.Sh. Kayumov

Journal of Tashkent Institute of Railway Engineers

The constant increase in the number of passenger trains has led to the fact that the semi-automatic blocking does not cope with the timely passing trains through the section. This article discusses the carrying capacity of railway section "N-B". The reserve capacity of this section is practically absent, the removal rate of passenger trains increases, which negatively affects the work of the entire railway section. Disposable and required carrying debility is determined. The method of increasing the capacity is chosen for each line depending on the given dimensions of movement, local conditions and technical and economic efficiency of different options.


Some Aspects Of Studying The Structure Of Construction Materials By The Method Of Mercury Purometry, Anvar Ishanovich Adilkhodjayev, I.A. Kadirov Sep 2018

Some Aspects Of Studying The Structure Of Construction Materials By The Method Of Mercury Purometry, Anvar Ishanovich Adilkhodjayev, I.A. Kadirov

Journal of Tashkent Institute of Railway Engineers

The article gives a classification of methods for controlling the porous structure of materials. The parameters of the porosity of aerated concrete were investigated by the method of mercury porosimetry. The method of mercury porosimetry is based on the fact that a liquid that does not wet a solid penetrates into its pores only when exposed to external pressure. The total porosity of aerated concrete according to mercury porosimetry is 49.28%


Comparative Analysis Of Road Roughness Specifications, Abduvokhid Yunusov, Narikawa Kazuo Jan 2018

Comparative Analysis Of Road Roughness Specifications, Abduvokhid Yunusov, Narikawa Kazuo

Acta of Turin Polytechnic University in Tashkent

In this paper, it is given that comparative analysis of road pavement roughness specifications between Uzbekistan and Japan. Road roughness measurement methods and acceptance values in construction and maintenance were analyzed. Based on comparative analysis, we developed recommendations about pavement roughness measurement methods for road authority of Uzbekistan.


Iri Roughness Index Requirements For Highway Functional Classification, Abduvokhid Yunusov, Jamshid Sodikov Jan 2018

Iri Roughness Index Requirements For Highway Functional Classification, Abduvokhid Yunusov, Jamshid Sodikov

Acta of Turin Polytechnic University in Tashkent

The paper reviews the role of highway functional classification in pavement management. Predominantly, technical classification is used in pavement management in CIS countries. The paper raises importance of highway functional classification in pavement maintenance in order to efficiently manage road network. IRI roughness index is widely used to monitor, assess road condition, analyze life cycle of the pavement. Authors proposed IRI values according to highway functional classification.
