2014年发布的《消防给水及消火栓系统技术规范》( GB50974—2014)相较于以往规范,针对地铁车站的消火栓系统提出增加室外消防水量、明确临时高压消防给水系统的稳压装置参数及消火栓按钮不宜作为直接启动消防水泵的开关的描述。通过对新增要求的理解,以实践设计经验对地铁消火栓系统设计方案进行研究分析,结论：地铁工程室外消防水量在双路市政水源的情况下可利用由市政水源接出的室外消火栓满足水量要求,否则需设置消防水池；临时高压系统的稳压装置流量取值宜为1~2 L/s,静水压力大于0.15 MPa且高于设定压力值0.07~0.10 MPa,储水容积宜为150~300 L；消防泵启泵按钮应保留。
2014年髮佈的《消防給水及消火栓繫統技術規範》( GB50974—2014)相較于以往規範,針對地鐵車站的消火栓繫統提齣增加室外消防水量、明確臨時高壓消防給水繫統的穩壓裝置參數及消火栓按鈕不宜作為直接啟動消防水泵的開關的描述。通過對新增要求的理解,以實踐設計經驗對地鐵消火栓繫統設計方案進行研究分析,結論：地鐵工程室外消防水量在雙路市政水源的情況下可利用由市政水源接齣的室外消火栓滿足水量要求,否則需設置消防水池；臨時高壓繫統的穩壓裝置流量取值宜為1~2 L/s,靜水壓力大于0.15 MPa且高于設定壓力值0.07~0.10 MPa,儲水容積宜為150~300 L；消防泵啟泵按鈕應保留。

The Technical Code for Fire Protection Water Supply and Hydrant Systems ( GB50974—2014 ) published this year requires more outdoor fire fighting water in comparison with previous specifications and defines that the stabilizing device parameters of temporary high pressure fire protection water supply system and the fire hydrant button should not be used as switch to directly start the fire pump. Based on the understanding of the new requirements, the researches and analysis on the design of metro fire hydrant system through practical design experiences, the paper concludes that subway engineering outdoor fire water with dual municipal water sources can be used to meet the subway water requirement, and otherwise fire pool has to be provided. The voltage stabilizing device flow value of the temporary high pressure fire protection water supply system, should be 1 ~2 L/s, the lift should be greater than 0. 15 MPa and higher than the set pressure value of 0. 07~0. 10 MPa, and the volume of water storage should be 150~300 L and fire pump start button should be retained.
