广深港客运专线福田站及相邻区间隧道为单洞双线隧道，具有时速高、断面大、阻塞比小、活塞效应弱和散热量大的特点。为保证隧道内人员舒适性要求，必须解决隧道内温度和新风量控制等关键技术问题。从区间和车站活塞风井设置、风井面积及车站排热风量3个方面进行研究，主要结论如下： 1）隧道内共需设5处活塞风井，分别为益田路1#风井和2#风井、福田车站两端活塞风井、皇岗公园风井； 2）福田车站两端活塞风井面积均为60 m2，其余3处活塞风井面积均为40 m2； 3）福田车站排热风量为540 m3/s； 4）优化后隧道最高温度为39.3 ℃，人均新风量为76 m3/h，均满足设计标准要求。

The Futian Station and adjacent interval tunnels on GuangzhouShenzhenHongkong Passengerdedicated Line are singletube doubleline tunnels characterized by high speed, large crosssection, small blocking ratio, low piston effect and large heat dissipation. In order to ensure the personnel comfortable requirements inside the tunnel, the key technologies of controlling the temperature and fresh air inside the tunnel should be solved. The setting of piston shafts of intervals and station, shaft area and volume of exhaust air are studied. Some conclusions are drawn as follows: 1) Five piston shafts should be set inside the tunnel in total, namely shaft No. 1 and No. 2 on Yitian Road, one on both ends of Futian Station and one in Huanggang Park. 2) The shaft area on both ends of Futian station is 60 m2 respectively; and the other three are 40 m2 respectively. 3) The air exhausting volume of Futian Station is 540 m3/s. 4) The optimized highest temperature inside the tunnel is 39.3 ℃; and the perperson ventilation rates is 76 m3/h, which coincides with the design standards.
