Abstract:
Unknown geological disasters, such as water inrush and mud gushing, are often triggered by disclosing filling cavities in the constructions of karst developing tunnels. Advanced geological prediction methods, drilling boreholes surveying and TSP were adopted for the prediction of filling cavities. And a former designed supporting program was adjusted and optimized according to the prediction conclusions. Other advanced supporting measures were also taken to support the dangerous districts, such as advanced curtain grouting, small-pipe grouting and pipe-shed grouting. In addition, pile-cap-bridges were in troduced to handle the filling cavities under the tunnel. By this method, geological disasters were prevented, and construction loss was reduced, so that the construction safety of the tunnel was guaranteed.
Key words: advanced geological prediction; filled cavern; controlling method of geological disasters
