The issues of bearing structures reliability for energy lines are of special importance in case of the use of single post horizontally loaded pile foundations of power lines and contact system supports. The required level of operational reliability of single post horizontally loaded supports in case of variability of strain-strength features of foundation soils along the route may be provided by using optimal sizes and number of foundation beams creating additional reactive impedance of soil to the loaded support. Foundation beams laid in soil perpendicular to a horizontally loaded support for increasing its bearing capacity are rather widely used. Though the issues of technical and economic substantiation of the choice of optimal sizes and number of beams influencing the strain and bearing capacity of power lines and contact system supports haven’t been studied enough. Basing on the experimental and theoretical studies the authors proposes his assessment of technical and economical efficiency of the use of foundation beams depending on their geometrical parameters, the amount and height of horizontal loading on a support.
