Abstract：Research purposes:Recently more lightning failures happened on the traction network for high － speed railway，which endangered the security of railway operations and personal． By the model of the striking distance method，the paper quantitatively calculates the total number of trip － out under the typical layout of the viaduct traction network for high － speed railway．
Research conclusions:The results show that the total number of trip － out will be high in the typical layout of traction network．which will be 25． 37878 times per 100 kilometer per year． Among them，there are 25.1508 times per 100 kilometer per year caused by striking on positive feeder，account for 99.1 percent．Finally，the paper promotes a improved optimization schemes of the typical layout of traction network ，Take first scheme as an example，the total number of trip － out have only 13.2579 times per 100 kilometer per year． Compared with the typical layout of traction network，the total number of trip － out decreased by 52.2 percent，so which have the important reference value for lightning protection in the future．
