摘　　要：近年来,我国大城市的综合管廊建设正在快速发展。但是,对于综合管廊消防灭火系统的设计与建设,各地做法不一。通过对我国近年来设计及建成运营的综合管廊内部纳入管线的种类和工作状态进行调研,分析了综合管廊内部火灾的起因和特点,并依据我国现行各类技术规范及工程实例的分析,提出:建设规模较小、覆盖面积较小、电压等级低的电力电缆综合管廊,可采取有效的工程措施而不设置自动灭火系统装置;对于建设规模较大、覆盖面积较大,内部纳入的电缆电压等级较高的综合管廊,除采取有效的工程措施外,还应采用移动式水喷雾消防灭火系统。With the development and building of large cities in China, multi-utility tunnels are is constructed in many cities, but they are different in design and construction of fire control system from place to place. In this paper, the reasons and characteristics of fire accidents in multi - utility tunnel are figured out by analyzing the type and function of pipelines installed in it. Meanwhile, based on the comprehension of codes and the analysis of projects, the authors propose that, for the construction of multi - utility tunnel with small scale, small coverage or low voltage grade power, effective measures can be taken to avoid the installation of automatic fire extinguishing system, while, for the construction of multi -utility tunnel with large scale, large coverage or high voltage grade power, movable water spray fire extinguishing system is expected to be used besides the application of effective measures in construction.
