| Abstract: | In this paper,main hydrogeological issues in detrital rock section of No.7 tunnel of the South Main Line of the YRDP are analyzed to guide the design and construction of the tunnel and to reduce the risking.The analysis is performed from the fields of engineering geological condition,hydrogeological condition,type of ground water,water bearing capacity of each aquifer and its existing way,runoff,recharging,discharging and so on.The main hydrogeological issues in No.7 tunnel are:outgush from the tunnel,abrupt discharge of the fault,water pressure outside the tunnel,poisonous water quality.In addition,the influence of ground water on the property of engineering geology of the soft rock,the influence of tunnel drainage on regional hydrogeological environment,and some corresponding methods for solving these problems are given by the author finally. |
