Abstract
Introduction. The article is devoted to the development of the economic-mathematical model of the technological process of the trench foundations’ construction, the indicators of which are related to the machine parameters, ground conditions and construction conditions.
Materials and methods. As a criterion of optimality, the specific energy intensity of the process, which is included in the system indicators, is chosen. Dependencies are established in the research, which determine the correlation of the economic parameters of the drilling process (the cost of the machine, the wages of workers, the standard cost parameters) and the main parameters of the machines, namely power and speed.
Results. As a result of experiments on the full-size test bench and the experimental model of the machine, theoretical dependences are confirmed, namely, the minimum specific energy intensity and the resulted costs, which are determined depending on the speed of penetration and the power used.
Discussion and conclusion. The developed technique could be used to optimize parameters and other constructions and road machinery, which are not limited to the purpose of the present research. The technique is based on determining the optimal values of the penetration rate and the amount of consumed power, corresponding to the minimum given costs.
