The design and flood flowing safety measures of the metro station in the flood district, such as scour protection, flood control, collision prevention and floating resistance, are studied based on the flood control evaluation on the Dongzhuang Station of the Shijiazhuang Metro Line 1 Project (Phase Ⅱ). Then feasible design measures are put forward to meet the requirements of flood control evaluation during different flood return periods. The design scope for main works includes: increasing the burial depth of the station, using the retaining piles as the anti-floating piles, and adopting the heightened anti-flooding retaining wall and anti-flooding baffle. Additionally, the civil air-defense door is also used as the flood gate in case of the unelevated ground at the entrance / exit in auxiliary works. Finally, the base slab at the entrance / exit is lower than the area below the maximum scouring line, the counterweight is backfilled in the void space, and the integral rigidity of the auxiliary structure is enhanced.
