f New technology of bases and foundations construction with soil thermal strengthening by a microwave field

A new way of soil thermal strengthening with a microwave energy has been developed last years. By this way heat is transfered into soil by means of radiation. This essentially differs the way from the traditional thermal ones, by which thermal energy is transfered by heat carrier through the soil macropores by convection. Microwave radiation penetrates into the soil to a sufficiently large depth that can be varied, the process is accompanied with the intensive absorption of electro-magnetic energy and vibration of elemental particles of minerals relative to nodes of a crystaIlic grid. As a result, a threedimensional heating of soil mass for a short time interval takes place.
