摘　　要：《城市综合管廊工程技术规范》(GB 50838—2015)规定,"干线综合管廊中容纳电力电缆的舱室;支线管廊中容纳6根及以上电力电缆的舱室应设置自动灭火系统;其他容纳电力电缆的舱室宜设置自动灭火系统"。目前国内综合管廊设置的自动灭火方式有水喷雾、细水雾、超细干粉、气溶胶等多种方式,但各种方式都有其限制条件和优缺点,综合管廊内的自动灭火方式的选择是行业内争议较大的问题之一。在对几类自动灭火方式进行应用比较基础上,总结了各类自动灭火系统的设计要点,并结合深圳前海合作区综合管廊的实际情况,通过对比分析,认为全域采用高压细水雾自动灭火系统,在后期运营、使用性能及造价费用等方面更具有优势。According to the Technical Code for Urban Utility Tunnel Engineering（ GB 50838 -2015 ）, the trunk utility tunnel which contains the power cable and the branch utility tunnel which contain six or more power cables should be set up automatic fire extinguishing system; other compartments are recommended to set up the fire extinguishing systems. At present, there are several kinds of automatic fire extinguishing system including water spray, water mist, ultra-fine dry powder, and aerosol. However, each mode has its limitations, advantages and disadvantages. So it is arguable to select the automatic fire extinguishing method in the utility tunnel. Basing on the application comparison of several types of automatic fire extinguishing methods, the key design points of various types of automatic fire extinguishing systems are summarized. Combination with the situation of the utility tunnel in Shenzhen Qianhai Cooperation Area, through comparative analysis, the overall use of the high-pressure water mist automatic fire extinguishing system is more advantageous in terms of post-operation, performance and cost of construction.
