ANALYSIS OF INTERFERENCES TO WUSHI SEISMIC MULTI-COMPONENT BOREHOLE STRAIN OBSERVATION

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.
