| 摘 要： | 根据多分量钻孔应变的观测原理,从理论和实际观测中分析了水厂抽水、标定、同机柜检修仪器的相互影响、数采死机重启数采、天气突变打雷等对多分量钻孔应变观测的影响。分析表明,钻孔应变观测值波动时间与各干扰时间基本吻合,因此认为水厂抽水、同机柜检修仪器、天气突变打雷等对多分量钻孔应变观测会造成一定程度的干扰。

| Abstract: | According to the principle of the multi-component borehole strain observation,the interferences of water work pumping,calibration,repairing of equipments in the same cabinet,digital acquisition system restarting,abrupt change of weather and thunder to the multi-component borehole strain observation are analyzed.Analysis shows that the fluctuations in borehole strain observations are basically consistent with the interferences;So that,the water works pumping,repairing equipment in the same cabinet,thunder and other weather changes lead to the interferences to the multi-component borehole observations to a certain degree. |
