摘要: The topic of this paper is the tunnel heading stability with groundwater flow towards excavation face. starting point a formula for minimum face pressure as considered by other researchers. It shown that some numbers, used in formula, need further calibration. In study, calibration done finite element analyses. Pore pressures are solved simple steady-state calculation and support obtained from nonlinear elastoplastic failure analysis. Both size fineness mesh studied full detail, they condition accuracy calculations.
