摘　　要：北京南口跨断层流动水准监测场地布设于南口—山前断裂与南口—孙河断裂交汇处。运用前人地质构造研究成果、监测资料和野外地质考察资料等,研究了南口跨断层流动水准场地监测和布设状况、结果表明:(1)监测场地存在未跨断裂测线;(2)4号测点不为基岩点且可能在断裂带内;(3)测线巨大突变异常是大量降雨所致,不为前兆异常或断裂活动。Cross-fault flow level site of Beijing Nankou laid the interchange of Nankou mountain fault and Nankou Sunhe fault. In this paper,the monitoring and layout of cross-fault flow level site in Beijing Nankou was studied,using the geological structure of previous research,monitoring data and field geological survey data,etc.. Result showed that：（ 1） No cross-breaking survey line existed in cross-fault flow level site in Beijing Nankou.（ 2） No. 4 measuring point was not bedrock point and within the fault zone.（ 3） Measuring line large anomaly was caused by huge rainfall,not precursory anomaly or fault activity.
