Calculation methodology of metal wedge-slot rod locks
Authors:
Abstract
It is known that the anchorage strength of rod locks is one of the most important conditions for the performance of the rod support. Soviet and foreign researchers define the parameters of metal wedge‑slot rod locks differently. The use of such rods is considered expedient mainly in rocks of medium strength (with a coefficient of strength f according to M. M. Protodyakonov from 5 to 8) and to a lesser extent – in strong rocks (f from 8 to 12). However, to date there is no published methodology that is simple and convenient for practical calculations.
