ON DETERMINING SOIL RESISTANCE IMMERSION OF MODEL PILES WHEN DRIVING
The results of the theoretical solution of the problem of determining the resistance of the soil to the impact immersion of the pile model under impacts by the falling load are presented. The problem is solved on the basis of the energy balance equation for the process of interaction of the striker, pile and soil with impact contact. In this case, the following force factors were taken into account, namely, the force of the structural friction of the striker against the guide, the friction force with an eccentric application of the shock load on the model, the force of air resistance to the movement of the striker, and the force of soil resistance to the penetration of the model. A formula has been proposed that allows one to determine the force of dynamic resistance of the pile model when driving it.
