Abstract
Taken a double-cable utility tunnel as an example,the functional requirements of each section of fire protection,ventilation,power supply and distribution,drainage,escape and hoisting.It is believed that the overall layout of the utility tunnel should be optimized based on production and operation requirements;Combined with the integrity of the flow,the node of escape and hoisting and section design are analyzed from the aspects of pipeline entry,aily inspections,emergency evacuation,etc.to provide design key points;Some safety hazards of water log-ging,falling,and evacuation obstacles that may occur during the design are discussed.The improvement ideas of detailed practices is briefly described,which can provides references for similar projects in utility tunnels to en-hance the operational service quality.关键词
