Design principia of control drainage on mountain tunnel;

Comparison of the application of water proof and drainage construction in regional tunnel of metro and mountain tunnel;

Plane numerical analysis of mechanical behaviors of lining structure under high hydraulic pressure in mountain tunnel;

Wushaoling long and deep-buried tunnel passes through the east foot of Qilian Mountain,with the length of 20 050 m and the maximum burial depth of 1 050 m.

Taking Changlingguan tunnel as an example,the author presents some geology prediction methods that are suitable for the tunnel and are widely used on Hefei～Wuhan passenger-dedicated railway in terms of working principle,applicability,advantages/disadvantages and application results,which can provide reference for the geology prediction of long tunnels and underground works in the future.
