摘　　要：华北某坝静力水准系统运行过程中,发现系统的测点测值异常,不符合坝体实际的运行变化规律,与人工比测结果不符。经现场检查和仪器测试,未发现异常情况。经过进一步分析、判断,发现工作基点(双金属标)、中间传递点运行异常是其中的主要原因,个别测点是由于仪器本身运行异常所致。针对引起异常的几个方面原因,采取相应的措施进行处理。A static level of the dam in North China during system operation,system point measurement value logging exception is found.It does not meet the actual running of the dam changes,and is inconsistent with the artificial log results.Field inspection and instrument testing,no anomalies are found.After further analysis and judgment,basis points（bimetallic standard）,intermediate delivery points run exception are the main reasons.Individual measuring point is caused due to the abnormal operation of the instrument itself.For several reasons causing the exception,appropriate measures are taken for processing.
