摘　　要：文章基于地铁工程采取各种举措降低建设成本的大趋势,对目前地铁工程常规的消防给水系统设计方案进行优化。方案借鉴工业厂区、居住区等集中设置消防泵房,提出采用一套临时高压消防给水管网向多栋建筑的消火栓系统供水的消防模式,重点探讨地铁工程全线划分成若干个消防单元,设置消防给水集中供水的可行性;在节能降耗方面提出了取消稳压泵、稳压罐,由市政给水直接进行稳压的设计方案,从技术可行性、安全可靠性和全生命周期成本等层面进行分析,实现降本增效,节能减排,为后续地铁项目提供设计参考。Based on the general trend of taking various measures to reduce construction cost in subway engineering, this paper optimizes the design scheme of conventional fire water supply system in subway engineering. The scheme refers to the centralized setting of fire pump rooms in industrial plants and residential areas, and proposes a fire fighting mode of using a set of temporary high-pressure fire water supply pipe network to supply water to the fire hydrant system of multiple buildings. It focuses on the feasibility of dividing the whole subway project into several fire fighting units and setting up centralized water supply for fire fighting. In terms of energy conservation and consumption reduction, the design scheme of canceling pressure stabilizing pump and pressure stabilizing tank and directly stabilizing pressure by municipal water supply is proposed. The technical feasibility, safety, reliability and full life cycle cost are analyzed to achieve cost reduction and efficiency increase, energy conservation and emission reduction, in order to provide design reference for subsequent subway projects.
