| Abstract: | The whole length of No.7 tunnel in the South Main Line of the YRDP is 43.5km,of which 28.5km cross the syncline core area,the level of ground water in this area is 50 300m higher than that of the tunnel line.The water bearing stratum and its tectonic characteristics along the tunnel line,aqueous petrofabrics and its water enrichment feature,regional water resisting layer,dynamic circulation of the ground water,cause of water gushing after the tunnel excavation and water gushing phenomena of the adjacent tunnel are analysed.In addition,the amount of water gushing of No.7 tunnel is estimated and predicted.Finally,the factors influencing construction and the method of excavation for tunnel are explained briefly. |
