In this study a critical section of the Pahang—Selangor raw water transfer tunnel under high overburden stress creates a zone of rock failure along the sides of the tunnel. This zone damages the steel fiber-reinforced shotcrete lining, and the observed failure depth in this zone is approximately 0.3 m. Elastic analysis model, elastic-perfectly plastic and elastic-brittle plastic models (D = O and m = 0.11) and instantaneous cohesion-softening friction-hardening (CSFH) model with parametric study are implemented to describe the influence of strength parameters on the extent, shape and depth of failure and investigate which parameters can simulate actual failure depth. As a result, the CSFH model results show good agreement with the observed depth and shape of the failure.
