By means of specialized maps it is obviously possible to assess geological profile of building ground in general, and separate sites of project facilities. The assessment of geological profile of territory of cities is impossible without geoinformation technologies at the present time. Improvement of mapping services and technologies of GIS software are widely used for engineering-geological mapping, development plan of territories, forecasting dangerous natural processes and assessment of various risks. However introduction of geoinformation technologies and special engineering-geological mapping in the Republic Kazakhstan is underdeveloped and does not play a leading role in engineering practice. The article addresses formalization of the process of creating special geotechnical maps in GIS as a certain step-by-step description of the process, based on a number of principles that determine the characteristics of map indicators and the methods of mapping. Special geotechnical maps are a basis for the decision of practical problems connected with an arrangement of constructions on the building ground, a detailed planning and project formulation of building blocks. The analysis of the existing methods of assessing geological profile of the built-up territory of the city was given in order to optimize the survey and engineering work on the construction of foundations, an example of the developed geoinformation database for the analysis of geotechnical properties of soils and the development of special geotechnical maps was given in addition. Also examples of types and the reasons of deformations of buildings and constructions caused by variations in the bases of foundations , besides the research works of the authors who developed their own methods of conducting engineering and geological surveys and special geotechnical maps have been analyzed and the concepts as «engineering-geological maps», «special geotechnical maps» have been defined.","PeriodicalId":168248,"journal":{"name":"BULLETIN of L.N.

With the entry of Kazakhstan enterprises into international markets and the opening of the Kazakh market for the goods of foreign firms, the problem of product quality has become a priority for domestic producers. Currently, there are problems in the implementation of the quality management system in Kazakhstan. Accordingly, the article discusses the problems of implementing a quality management system in the example of a company producing bentonite clay in Kazakhstan. The methods of observation, analysis, and synthesis, as well as the technique of interview with the head of the quality group, were used for the research. As a result of the research, the management system introduced in this enterprise was discussed, and the problems observed during the system implementation were presented, as well as recommendations for the company.","PeriodicalId":168248,"journal":{"name":"BULLETIN of L.N.

It is shown that the increase in the robust stability potential is the main protection factor guaranteeing the system from the regime of deterministic chaos with the generation of \"strange attractors\". Investigations of the control system with a high potential for robust stability are made by the gradient-velocity method of the Lyapunov function vector.

Currently, they are undergoing physical and moral wear and tear. The growth of production capacities of industry and the population emphasizes the need for intensive development of the energy complex using the technologies of the XXI century, while maintaining a technological balance between traditional energy and renewable energy sources [4]. The concept of development of the fuel and energy complex of the Republic of Kazakhstan until 2030 fully reflects these tasks and development approaches. In addition, the construction and reconstruction of distribution networks are due to the growth of a total load of consumers, which, even now, continues to increase rapidly. Concrete used in construction is an integral part of all types of construction and installation work. Thus, the concrete mixture used in the construction of energy facilities must have special properties and moisture-resistant characteristics, allowing you to solve specific energy problems, which include: reliability, durability, low electrical conductivity and other characteristics of concrete structures. High indicators of the above requirements are imposed in the places of installation of current-limiting reactors at electrical substations.","PeriodicalId":168248,"journal":{"name":"BULLETIN of L.N.
