Calculation of the natural tension of rock bolts due to rock creep

Abstract
For efficient operation of metal anchor rods, they are given an initial tension of about 3–4 t. Reinforced concrete solid rods are usually installed without initial tension; moreover, they work no less effectively than metal anchor rods. Steel-polymer rods with a plug lock are installed both with and without tension
