Abstract

Fiber reinforced shotcrete(FRS) is widely used in tunnel linings, which strengthen the rock surface and reduce the loosening of the rock strata. The advantages of FRS in tunnel linings are the unsusceptibility to crack, the benefit of shotcrete strength, and the superiority of toughness. In this study, the several evaluation methods of FRS toughness were investgated experimentally, which included the ASTM beam test, EFNARC square panel test and RTA round panel test. Especially, it was examined that the round panel test could fulfill the toughness evaluation of FRS.
