  • Engineering analysis of the calculated characteristics of the bearing capacity of driven and bored piles.

    The article presents the results of a comparative analysis of practical calculations of driven and bored piles, which have similar geometric parameters and common geological conditions of construction sites. Taking into account the peculiarities of the use of these piles and the available experimental data, the paper analyzes the calculated values of their bearing capacity and gives an engineering assessment of the results of the calculation. The quantitative difference between the determined parameters of the bearing capacity of piles - friction along the lateral surface and frontal resistance, is clearly shown in the constructed diagrams. So, when using the standard values of the coefficients to determine the bearing capacity of piles, we have a significant excess of this parameter for driven piles. The need to use more gentle methods of driving piles to the design depth leads to the possibility of using the technology of arranging bored piles, which have a lower bearing capacity with the same parameters as driven piles. This feature should be taken into account in engineering calculations when selecting the optimal dimensions of bored piles.

  • The state of the automation level of energy facilities and solutions aimed at its improvement

    This paper analyzes the state of the automation level of energy facilities. The most rational method of assessing the level of automation is given: consideration of each energy facility (generating enterprises, transport companies, consumers) separately for the most effective assessment. The analysis of the level of automation of generating companies on the example of thermal power plants is given. A solution aimed at increasing the level of automation is proposed. The analysis of the level of automation of transport companies and consumers on the example of thermal energy is also given. The ways of increasing the level of their automation aimed at improving the efficiency of transmission and use of energy are proposed. The article presents a number of advantages of the introduction of automated systems at energy facilities on the example of an automated dispatch control system at power plants and substations. A number of the most promising solutions for increasing the level of automation of energy facilities are also presented.
