Calculation of natural tension of fastening rods due to rock creep
Authors:
Abstract
For the efficiency of metal locking rods, they are given an initial tension of about 3-4 tons. Reinforced concrete solid rods are usually installed without initial tension; and they work no less effectively than metal locking rods. Steel-polymer rods with locking plugs are installed with or without tension.
