Abstract


The tunnel gushing disasters are most common in the tunnel during construction and operation of geological disasters , water gushing prediction and forecast of the current problems to be solved . In this paper, Shijiazhuang-Taiyuan Passenger Dedicated Line Nanliang tunnel and the Taihang Mountain Tunnel as research background , to the construction lots gushing forecast for research purposes , a comprehensive analysis of first the South beam tunnel and the tunnel of the Taihang Mountains hydro-geological conditions and engineering geological conditions , combined with the engineering geological conditions unit partition and segmentation on Taihang Mountain tunnel South beam tunnel and hydrogeological conditions ; -depth study of the karst tunnel gushing disasters factors , the main factors affecting the geological structure, lithology , rock category , tunnel length and buried deep , surface environmental characteristics and weather conditions . The basis of this theoretical analysis , a more comprehensive analysis of the theory and method of predictive of tunnel discharge , study and compare the advantages and disadvantages of the various methods and scope of application . South beam tunnel and the tunnel of the Taihang Mountains hydrological geological conditions and engineering geological conditions , combined with the actual situation of the site survey , the Analytic Hierarchy Process to determine the rights of each factor weight , gushing water level of the South beam tunnel and the tunnel of the Taihang Mountains of fuzzy mathematics comprehensive evaluation method and water gushing range forecast , last Compare randomness method and finite element method predictions . The findings of this thesis the South beam tunnel and the Taihang Mountain Tunnel and other karst tunnel prediction of water inflow has a certain reference value .
