Abstract
In order to find out the water-rich situation of Gudoushan Tunnel,the water-rich section of Gudoushan Tunnel is detected by advanced drilling and transient electromagnetic method;according to the water-rich situation of Gudoushan Tunnel,the experimental study on on-site grouting water stop reinforcement is carried out,and the key technology of grouting water stop in rich water area is put forward.Considering the balance between tunnel groundwater discharge and vegetation ecology,the allowable discharge of groundwater in the tunnel site is given.The research results show that the common cement-water glass double slurry is selected for drilling to expose the area with large water inflow in the tunnel,and the effect of grouting is ensured,and the final pressure of grouting is determined to be 5～6 MPa by comprehensively considering the factors such as groundwater pressure,formation lithology,properties and concentration of slurry,grouting diffusion radius and so on.According to the requirements of vegetation and ecological environmental protection,according to the restoration of the original groundwater level within 2 years,the allowable discharge of groundwater in the flood discharge area,the reservoir connection area and the tunnel near the outlet area was determined.关键词
