Understanding the hydro-mechanical (HM) coupling grouting process in fractured rock masses is vital for improving grouting effects. In this paper, a hybrid formulation of the unified-pipe network method coupled with zero-thickness interface elements is developed for simulating fracture grouting, nam...
