- Abstract:
-
There are ten types of Karstic Features in Wuzhi mountain tunnel.The evolvement of karst in Wuzhi mountain was analyzed based on geology investigation.Water gushing in each sections of the tunnel was predicted by using methods of runoff modulus,effective infiltration of rainfall at different time intervals annually and dynamics of groundwater.And dynamic changes of water gushing were also analyzed in the tunnel before and after its completion.Water gushing in Wuzhi mountain tunnel have five sections.And the large gushing yields from the fault ‘8.6’ at the entrance section and from the Gypsum breccia at the exit section cause serious effects on the construction and environment in the tunnel.
