摘　　要：以VOF模型耦合k-ε湍流模型的方法,建立地铁车站水侵过程的数值模拟模型,研究隧道防淹门开启或关闭两种不同条件下,入口处积水深度为50cm和30cm高度时,洪水入侵地铁车站的推进过程。模拟结果表明,数值模拟方法适合用于地铁车站水侵过程的研究;与30cm深度相比,50cm深度时车站内部洪水漫延和聚集的速度更快;防淹门开启的工况中,洪水入侵前期蔓延速度较快,且一定条件下,洪水在车站内部总流量可达到平衡;当洪水入侵过程达到平衡后,洪水主要聚集在站台层,且地面积水高度为50cm的入侵洪水总流量更多,造成后果更为严重;防淹门关闭状态下,洪水入侵前期过程与开启状态区别较小,但后期洪水更多地滞留在站厅层区域。The VOF model is combined with the k-ε turbulence model to build a numerical simu-lation model of the water invasion process,and the two different conditions of the tunnel flood gate be-ing opened or closed are studied.When the depth of water at the entrance is 50 cm and 30 cm,the process of flood invasion of subway station is analyzed.The simulation results show that the numerical simulation method is suitable for the study of water intrusion process in subway stations.Compared to 30 cm depth,flooding inside the station spreads and gathers faster at 50 cm depth.Under the condition that the flood door is opened,the rapid spread of flood intrusion in the early stage is relatively fast,and under certain conditions,the total flow of floodwater in the station can reach a balance.When the flood intrusion process reaches equilibrium,the flood water mainly accumulates at the platform level,and the total flow of the intrusive flood with a water height of 50 cm on the ground area is more,resulting in more serious consequences.When the flood door is closed,the early process of flood intrusion is less different from the open state,but the later flood is more trapped in the station hall level area.
