Mechanics of Contact Mode Drilling Balls with a Primary Basis According to Numerical Method of Boundary Elements

Abstract

Construction is one of the main sectors of the national economy of any state, it provides creation of new, expansion and reconstruction of existing fixed assets. Construction plays the most important role in the development of all sectors of the country, in raising productivity, raising the material well-being of the population.

The problem of load-bearing capacity of the basics still remains relevant due to the growing volume of industrial and civil construction, reconstruction and the need to design reliable and economic structures. Therefore, the development and implementation of more sophisticated and cost-effective methods of calculating and designing foundation structures aimed at identifying and implementing their reserves is an important and relevant problem of construction science. Taking into account the nonlinearity of deformation of the foundations in combination with the methods of their optimal design allows to raise the adequacy of calculations and to obtain significant savings of concrete and reinforcement.

Due to the growing volume of use of drilling piles (including extensions), it is necessary to develop modern predictive methods for determining their bearing capacity with the involvement of computers, because the main task in the design of structures is the engineering assessment of bearing capacity of soil bases. Therefore, the development of the scientific basis for the calculation of dispersed soil using elastic-plastic dilatancy model is a relevant trend of modern foundations.

In the work, the presentation of the prediction of the bearing capacity of the drilling pile with extension is presented according to the numerical method of boundary elements (MGE) from the standpoint of mechanics of dispersed elastic-plastic medium. The solution of the nonlinear problem of predicting the bearing capacity of a drilling pile with extension is of scientific and applied importance and is closely related to the analysis of soil VAT.
