In the article there are results of modeling of the work of steel concrete screw and drilling piles interacting with the soil massif . For the purpose of modeling the mathematical apparatus of finite element method was used in realization of the license certified program complex Lira- soft v.10.6. The process of modeling of the subsidence is described. There is a presentation of three options of interaction of soil and piles. Draft magnitudes of single piles from external load and from negative friction forces are found.
Keywords: Steel concrete screw pile, drilling pile, soil massif, subsidence, Lira-soft, draft, deformations, movements, tensions
The article is devoted to the problem of the identification of the Black Sea – Caspian region as a special segment of the World Space in the postbypolar system. The Great Limitrophe conception developed by V.L. Tsymbursky and S.V. Khatuntsev is used as «the structural frame» for understanding modern peculiarities of this region. The author outlines two aspects of its identification: geopolitical and geocivilozational. He also introduces the key concept «limitroph territory» adapting it to the specific region. The key concept involves two other concepts – «shatterbelt» and «(inter)civilizational split zone». The article contains brand new facts on the Black Sea – Caspian region problem.
Keywords: «big political space», geopolitics, Black Sea – Caspian region, Great Limitrophe conception, limitrophe-territory, «shatterbellt», civilizational layer, «(inter)civilizational split zone».
The results of physico-chemical studies of micro-and macrostructure of fine-grained concrete hard pressing, used for making bread products for pavements . To improve the quality indicators ( bending moments ) in the fine-grained concrete mixtures were introduced damping additives such as ash microspheres - component slag mixtures . The essence is the replacement of the dense grain mixture with an equal volume of mineral supplements. Ash microspheres have a reduced strength and modulus . Of interest are preserved particles of hollow spheres of additive used , they are responsible for the effect of branching cracks. For experimental studies the author has developed a special method for determining the persistence of particles of ash microspheres after exposure compacting pressure. The quantitative ratio between the phases and composition of the mineral phase were determined by X-ray diffraction and optical microscopy.

Features of a site of construction of constructions of seaport of Taman are considered. The settlement scheme of influence of new construction of point of loading on an existing complex of tanks is proved. The final and element model of a coastal zone with an arrangement of underground designs of existing and port constructions under construction is constructed. Results of calculation intense the deformed condition of the soil massif and construction designs are given.
Keywords: the pile bases, the soil basis, modeling, a deposit, intense the deformed condition.
The main subject of work is consideration of the features of strategic partnership model formation between the state, employers and institutions of professional education system at the Russian labor market. In this study is revealed that the current Russian labor market is characterized by an imbalance of supply and demand for labor in specific vocational skill groups. To solve this problem the need to improve the interaction between the state, employers and institutions of professional education system is proved. A comparative analysis of the main forms of partnership subjects is given. The capabilities and the need for a model of strategic partnership is identified. The features of the formation strategic partnership model at the Russian labor market are investigated. The implementation of the strategic partnership model will promote effective, mutually beneficial and long-term partnership of these subjects in the labor market.
Keywords: labor market, strategic partnership, the labor market imbalance, state,employers, institutions of the professional education system
This article discusses the definition of the bearing capacity of piles to strengthen the base of the building, with the considering differential settlement, with formulation of a nonlinear problem of a residential building in Belovo, Kemerovo region. These results were used at develop methodology for restoration of buildings and structures on the basis of monitoring
Keywords: differential settlement, bearing capacity of piles, physical nonlinear formulation, finite element method
