Abstract: The Longtan tunnel which is being constructed is the second longest expressway tunnel in China by now. The stratum of the tunnel is complicated. And there are bad geological conditions such as partial press, karst, fault, high in-situ stresses and so on. In the paper, some key technologies are simply introduced; and some measures are presented to solve the possible problems during the progress of construction of the ninth bid. These measures can ensure the quality and the time limit for the project.

Key words: tunneling engineering, expressway, bad geological conditions, construction scheme
