摘　　要：文章通过对电力电缆隧道内发生火灾原因和特点进行分析,并结合以往线路设计经验和规范要求,通过主动防火和被动防火的角度进一步思考和分析,从火灾监测、电缆选型,接头布置优化等方面提出对隧道内电缆防火的方案构想,实现电缆隧道消防“预防为主、防消结合”的设计原则。This paper analyzes the causes and characteristics of fire in power cable tunnel,and combines the previous line design experience and specification requirements.Through further thinking and analysis from the perspective of active and passive fire prevention,this paper puts forward the scheme conception of cable fire prevention in tunnel from the aspects of fire monitoring,cable selection,and joint layout optimization,etc.The design principle of"prevention first,prevention and elimination combined"is realized.
