蚌埠监测中心井水位、水温干扰度评估

Assessment of disturbance of water level and temperature of Bengbu monitoring center well

蚌埠监测中心水井数据产出连续可靠,近一年由于地下流体动态受到干扰,影响了监测预报效能。本文通过干扰度方法,评估蚌埠监测中心井水位、水温干扰度,结果表明,水位、水温的相对异常量多超过正常变幅。与两次震例异常比较后,发现仪器运行环境引起的干扰量仍大于震例异常量幅度,确定为是由观测技术系统干扰因素造成的。因此,干扰度评估可为今后水位、水温异常进行判别,又可为进一步保护台站周边环境提供依据。

Bengbu monitoring center well continuously gives reliable data.In the past year,however,the efficiency of monitoring forecast has been affected due to the interference of the dynamic state of the underground water.This thesis accesses the water and temperature of Bengbu monitoring center well through the analysis of its interference degrees.The results show that the relative anomalies of water level and water temperature have surpass the normal range.In comparison with two abnormal earthquake cases,the level of interference caused by the instrument operating environment remains larger than the amplitude of earthquake anomalies,which is identified as a result of the interference factors of the observation system.Therefore,the assessment of the interference degrees can both differentiate the water level and water temperature in future and provide basis for protecting the surroundings of the earthquake station.
