Investigation of the Reliability of Reinforced Concrete Overpasses of a Road Overpass 
Donbas National Academy of Civil Engineering and Architecture
Abstract. The scientific task of ensuring the reliability of road bridges is formulated in the article. Reinforced concrete regulation of bridges reliability in normative documents is analyzed. A model is proposed to forecast reliability of operated span structures of road bridges. This model is based on the actual reliability of bent elements at the time of technical survey. It is possible to determine the initial reliability, predict the change in reliability over time, and determine the remaining resource when reliability required is achieved. The requirements of normative documents are analyzed. Recommendations are given to designate the design value of safety characteristics of the bent elements of road bridges span structures.
Keywords: reinforced concrete road bridge, span structure, bending element, reliability, safety characteristics, durability.

The Role of Territorial, Geographic and Geopolitical Factors in Formation and Development of Regional Specific Features of Architecture of Buildings, Structures and their Complexes in Donetsk Region Cities 
Donbas National Academy of Civil Engineering and Architecture
Abstract. The article deals with the role of territorial, geographic and geopolitical factors in formation and development of regional specific features of architecture of buildings, structures and their complexes in Donetsk region cities at present stage of its contemporary history and during the preceding historic periods. In the article the composition of these factors and the nature of their impact on the typology and architectural and planning organization of buildings and structures are specified. The prospective lines of Donetsk region development under modern conditions are traced on the basis of the formation of specific cluster complexes having production and sectoral, transport and logistic, agro-industrial, educational production, recreational and touristic, historical and architectural nature, etc. The image and design features common for each of such complexes as well as the significant regional specific features should be reflected in the architecture of their buildings and structures. The present article examines the aesthetic features of compositional and artistic design of buildings and structures in Donetsk region which are influenced by the events and conditions of its contemporary historic period.
Keywords: geopolitical factors, regional specific features of buildings and structures architecture, modern Donetsk region territory, territorial and geographic position.

Intensification of Donbas Water Wells Operation by Pneumatic Impulsive Impact with Annular System of Filter Zone Regeneration 
Donbas National Academy of Civil Engineering and Architecture
Abstract. Nowadays there are many actual technologies for recovering the flow rate of water wells. It is known that the greatest effect is achieved by methods of impulse impact in combination with reagent treatment of filters and filter zones of water wells. The article considers the application of the pneumoimpulsive method for the flow rate recovering of water wells together with the method of annular regeneration system.
Keywords: water well, air explosion, annular flushing system, well filter, filter zone, air-lift pulp line.

Classification of Methods of Editing of Elements of Conveyer Galleries in the Conditions of Operating Enterprise 
Donbas National Academy of Civil Engineering and Architecture
Abstract. In the article the methods of editing of existent constructions of conveyer galleries are systematized under the conditions of operating enterprise, classification over of methods and methods of editing of conveyer galleries is brought taking into account their structural features and groups of factors, taking place at the reconstruction of operating industrial enterprises. The aim of work is development of methods of effective, structuring and engineering layout of process of editing of conveyer galleries design in the conditions of operating enterprise, providing the set reliability and resource-saving at erection of objects of building in the conditions of vagueness and the straitened terms of building district.
Keywords: conveyer galleries, assembling-technological process, method of editing, metallic constructions.

The Effect of a Partially Fixed Subsidence Ground on the Stress-Strain State of Structures 
Donbas National Academy of Civil Engineering and Architecture
Abstract. The article analyzes the existing methods of increasing the rigidity of the bases, formed by subsidence grounds. The results of experimental studies of the effect of the stiffness coefficient of partially anchored soil on VAT structures are presented. The regularity of the change in the coefficient of rigidity of the base Cz from the percentage of partial fixation of the sinking base along the height is established.
Keywords: subsidence ground, coefficient of rigidity of the base, physic-chemical method, additional efforts.

Determination of Subsidence Deformations According to Normative Documents of Russia and Ukraine 
Donbas National Academy of Civil Engineering and Architecture
Abstract. The article analyzes the method for calculating subsidence deformations from the external load and the soil’s own weight in accordance with the current regulatory documents of Russia and Ukraine. The results of a comparative analysis are presented taking into account the dimensions of the basement, the value of the external load on the base, the thickness of the subsidence layer and the relative subsidence of the soil. Proposals are made to improve the method of determining subsidence deformations.
Keywords: subsidence ground, subsidence, subsidence from external load, subsidence from own weight of ground, drawdown zone.
