新疆洞体形变数字化观测资料干扰分析

摘要

对新疆洞体形变数字化观测资料进行了分析,影响新疆洞体形变数字化观测资料的干扰因素主要有以下几点:(1)天气干扰.气压波动,降水(雨、雪),温度突变,刮风(含沙尘暴),雷电干扰.(2)环境干扰.观测室外部或内部环境因人为或其他因素造成的干扰.(3)人为干扰.调零、标定、检查、维修产生的人为干扰.(4)电干扰.电压不稳或强电流产生的电流冲击干扰.其中天气干扰和环境干扰是导致观测资料出现异常变化的主要因素.仪器故障、人为干扰、电干扰是导致数据丢失的主要原因.%Analyzing Xinjiang cave strain deformation digital observation data,it concluded that the interference factors lied in followings:(1) Weather factor.Fluctuation of air pressure,precipitation (rain,snow),temperature mutations,wind (Containing dust storms),thunder and lightning interference.(2) Environment factor.The interference of external or internal environment of the observation room or other factors.(3) Human factor including zero set,calibration,checking and maintenance.(4)Electricity factor.Voltage instability and heavy current interference.The abnormal change of observation data resulted in weather and environment factors,and because of instrument failure,human disturbance and electrical interference data lost.
