摘要
通过观测资料的连续率、潮汐因子内精度、自洽性检验、相对实地标定以及主要干扰因素分析,对芨芨台分量式钻孔应变观测系统的一致性和可靠性进行了评价。结果显示:①观测资料连续率高,精度达到了形变I类台的标准,但观测数据的自洽性检验结果相对较差,且不适宜进行相对实地标定。②温度和水位是主要的干扰因素,且水位在6—9月的急剧波动易导致数据失恰。
The consistency and reliability of Jiji Station component drilling strain observation system were evaluated through the continuity of observation data,accuracy of tidal factors,self consistency test,relative field calibration,and analysis of main interference factors.The results show that:①the continuity of the observation data is high,and the accuracy meets the standards of Class I deformation stations,but the self consistency test results of the observation data are relatively poor,and are not suitable for relative field calibration;②Temperature and water level are the main interfering factors,and the sharp fluctuations in water level from June to September can easily lead to inaccurate data.
