Abstract: The stability of a twin-tube highway tunnel is analyzed using improved discontinuous deformation analysis (DDA) method. By employing advancing front method, the triangular DDA blocks are automatically generated in the computational area. In this process, numerous artificial joints whose strength is higher than that of real joints come into being. In addition，the reinforcing effect of prestressed bolt on the surrounding rock is also taken into account. The numerical results are compared with the measured data, and they show pretty good agreement; therefore, it is shown that the improved DDA method is capable of analyzing stability of underground tunnels.

Key words: DDA, highway tunnel, stability analysis, artificial joint, prestressed bolt
