摘　　要：以恒力全球运营总部为例,对250m以下超高层建筑群的消防转输串联供水和半重力供水方式进行了全面分析与对比。立足于消防系统的关键环节,详细阐述了半重力给水临时高压集中供水方式的运行特点。拓展提出了一种新型的准重力给水方式,并对现行消防分区供水压力2.4 MPa提出突破诉求。Taking Hengli Group's Global Operation Headquarters as an example,the characteristics of transfer tandem water supply and semi-gravity water supply methods for super high-rise building groups below 250 m were analyzed.Based on the key aspects of the fire protection system,the operational characteristics of the temporary high-pressure centralized water supply method for semi-gravity water supply were described.This study proposed a new quasi-gravity water supply system and suggested a breakthrough to the existing fire compartment water supply pressure of 2.4 MPa.
