福州地铁4号线车站单端风亭方案探讨

福州地铁4号线省立医院和远洋路站因拆迁原因，无法设置常规的双风亭车站。为此提出单端设置风亭的方案。经过SES模拟计算单端风亭车站正常工况下区间隧道温度及通风量，阻塞工况下单端风亭区间温度，火灾工况下单端风亭区间排烟、烟气过站、活塞风压对站台门影响，单端长距离送排风均匀性等问题，通过有效的技术手段，在车站前后站间距不足1 km，不存在列车追踪的情况下，全高站台门系统单端风亭车站通风空调方案能满足要求。

Discussion on Single-end Wind Pavilion Scheme for Stations on Fuzhou Metro Line 4

Conventional Double-wind pavilion stations cannot be set in Fuzhou Metro Line 4 owing to the demolition of Provincial Hospital and Yuanyang Station; however, single-end wind pavilions are feasible. Following subway environmental simulations, effective technical measures are taken with respect to the temperature and ventilation volume of the tunnel in a single-end wind pavilion station under normal conditions and under blocking, to fume exhausts and crossing of single-end long-distance air delivering the influence of the piston wind pressure on the platform gate and to exhausting uniformity of single end wind pavilion in case of fire. Thus, ventilating and air-conditioning of the platform screen doors of the single-end wind pavilion station can meet the requirements under the condition that the distance between two stations is shorter than 1 km and train tracking is not considered.
