Analysis of the stress-strain state of a vertical ground electrode system for permafrost soils under pushing loads

The article proposes the design, design scheme and model of a vertical ground electrode system with lobe lugs for permafrost soils. was implemented using ANSYS software. In scheme, soil — is taken into account, elastic-plastic properties are account by Drucker Prager model. When modeling work foundation soils, Mises strength condition adopted, according to which equivalent stress calculated under material hydrostatic compression. following boundary conditions accepted: cylinder-shaped mass rigidly fixed along lower face side surface cylinder. Calculations made 5 standard sizes grounding conductors. Maps distribution stresses in metal structure (the rod petals-emphasis) received, movements determined. dependences between maximum lobes value displacement base established, as well amount movement earthing pad, at effective voltages reach critical values area where paddles adjacent rod.
