Abstract

Based on a different case of underground water seepage in the southern tunnel, the ground settlement of around tunnel under around-water seepage was analyzed by FLAC-3D. The stability time of the ground settlement of around tunnel was gained. And several situations, such as the location of the internal seepage flow, seepage flow ratio and ground water level, were taken into consideration. The influence of seepage flow inside the tunnel for tunnel surroundings was got.
