摘要

The defective geological conditions such as the karst water, fault, underground river, nature gas, ground temperature and ground stress are very serious in Deshenchang valley section of Qiyueshan tunnel. The great difficult and risk of tunnel construction is extremely rare in the history of mountain tunnel construction. So how to reduce incidence rate and loss of tunnel accident has become an urgent subject to be solved. In this paper the geological risk factors of Qiyueshan tunnel are classified and identified. Then the tunnel geological risk is assessed under its complex geological condition. The requirements and controlling process of geological risk assessment are also discussed. These achievements can provide useful reference for similar tunnel risk assessment engineering.
