摘　　要：本文通过对中庭车站消防安全目标、火灾时乘客疏散重难点、安全疏散模式及排烟量计算方法的研究,得出了在站台层孔洞两侧或中庭开口区域设置挡烟垂壁两种防烟分区划分方案、安全疏散策略及相应的防排烟系统设计原则,并通三维仿真模拟验证了研究结果的可行性,对中庭车站的防灾设计具有一定的借鉴意义。Based on the study of the fire safety objectives of atrium station, the key and difficult points of passenger evacuation in case of fire, the safe evacuation mode and the calculation method of smoke exhaust volume, this paper obtains two smoke control partition schemes, the safe evacuation strategy and the corresponding design principles of smoke control and exhaust system, which are to set the smoke retaining wall on both sides of the platform hole or in the area of atrium opening.The feasibility of the research results is verified by three-dimensional simulation, which has a certain reference significance for the disaster prevention design of atrium station.
