摘　　要：针对常用绘图软件对自动喷水灭火系统只能进行平面管网水力计算,不能进行立体管网计算的现状,提出了一种适用于机械立体车库自动喷水灭火系统的水力计算方法——主要节点压力平衡法。该方法依据主要节点压力平衡的原则,采用人工与软件相结合的方式进行水力计算,简便且易于操作。通过逐个节点压力平衡的人工精算验证其计算结果。结果表明该计算方法可对机械式立体汽车库自动喷水灭火系统进行较为精准的水力计算。应用该计算方法研究了干管及立管布置对机械式汽车库自动喷水灭火系统流量的影响,为其自动喷水灭火系统设计提供参考。A hydraulic calculation method for sprinkler system in mechanical stereo garage, which is the main node pressure balance method, is proposed in view of the fact that the common drawing software can only calculate the hydraulic network of plane network, but not the three-dimensional network. According to the principle of pressure balance of main nodes, the method combines manual and software for hydraulic calculation, which is simple and easy to operate. The calculation results are verified by manual actuarial calculation of pressure balance at each node. The results show that this method can be used for accurate hydraulic calculation of sprinkler system in mechanical stereo garage. At the same time, the influence of main pipe and riser pipe arrangement on flow rate of automatic sprinkler system in mechanical garage is studied by this method, which provides reference for sprinkler system design.
