Abstract

Shield tunnel construction will disturb the surrounding strata and cause stress release and adjustment, resulting in uneven settlement of adjacent buildings and even collapse. According to the geological conditions of Ji'nan Railway Line 2, a three-dimensional numerical model is established. The analysis shows that the influence of tunnel excavation on existing buildings decreases with the increase of the distance from the tunnel axis. After the tunnel construction, the displacement of the building is obviously increased. The soil around the tunnel is funnel-shaped in vertical displacement. The maximum settlement is 5.57mm which appears near the tunnel invert. The uneven settlement of the building is 1.6mm. These conclusions can be used to give some reference to similar shield crossing projects in the future.
