摘要(Abstract):
顶部集中排烟模式在特长盾构隧道中普遍应用。随着采用集中排烟模式的隧道距离加长,排烟阀预留孔洞增加,漏风点增多,一种新型排烟阀应用于实际工程。依托江阴靖江长江隧道,利用火灾动力学软件(FDS),采用数值模拟方法研究了盾构隧道顶部集中排烟模式排烟阀组内合理间距,分析了排烟阀处流场特性、隧道内排烟阀附近温度分布规律、排烟状态、质量流量和排烟效率。结果表明:随排烟阀组内间距增大,排烟道及行车道内会形成大规模的涡旋,且隧道内排烟阀附近纵向温度分布从“V”形变为“W”形;排烟阀组内间距变化对排烟阀的排烟状态、质量流率及排烟效率影响较小。针对本项目,综合考虑排烟效率、温度场分布规律及流场分布规律,建议排烟阀组内间距d不超过1.6 m(1a)。
