Abstract：Research purposes: According to the principle that urban mass transit has to give consideration to aerial defense, the analysis of the technical plan for the overhead contactwire in tunnel crossing the aerial defense facility is made forchoice of the safestandmostreliable plan to notonlymake the overhead contactwire smooth crossing the aerial defense facility, meeting the traffic requiremen,t ensuring the accepted currentwith high quality, butalso to enable the aerial defense facility switching its function in peacetime to the function inwartime.
Research conclusions:By analyzing the characteristicsof the defense partition doorand two deferentsuspension kindsof overhead contactwire, the plans are compared and selected. When the flexible suspendedwire is adopted, the inserted board should be equipped to the defense partition door. When the rigid suspendedwire is adopted, the obstruction board should be equipped to the defense partition door. If the outside junction of bus -barwire is connected, the rigid suspendedwire ispreferable to crossing the defense partition door. This scheme is adaptive to quick construction in both of peacetime andwartime, good to operation and maintenance and can obtain the good economic benefits and be used widely because the contactwire ismore integratedwith less components and parts.
