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