首先分析了华北地区跨断层流动形变监测场地布测现状及监测效能，继而依据跨断层流动形变测量规范及监测的可控性、均匀性、目的性以及监测场地监测效能等，结合该区域断裂活动及地震活动性研究结果，给出华北地区跨断层流动形变监测场地拟优化布设结果。该优化布设结果消除了华北地区跨断层流动形变网监测地震活动盲区，有助于提高该区跨断层流动形变网监测地震活动能力。

In this paper,the layout monitoring situation and monitoring effect of cross-fault mobile deformation monitoring site in North China are analyzed. Then,on the basis of the consideration of cross-fault mobile deformation measurement criterion,monitoring requirement of controllability,uniformity,purpose and monitoring sites' monitoring effect,etc.,and with the research result of local fault activity and seismic activity,the cross-fault mobile deformation monitoring site's layout optimization result is given in North China. This layout optimization result eliminates the monitoring seismic activity blind area of cross-fault flow deformation network and helps to improve the monitoring seismic ability of cross-fault flow deformation area network in North China.
