Abstract
In recent years in Chile, the use of fiber reinforced shotcrete (FRS) has been widely extended in underground works, particularly in tunnels for roads, mines and hydroelectric projects. In these projects, the design of the supports is mainly based on the modified Q–Barton method, which relates the rock mass quality to the minimum energy absorption capacity of the FRS, which is determined by the square panel test, with panels filled during spraying. However, to obtain these specimens, complex p...
