气象因素对倾斜仪观测干扰特征分析
Analysis of Meteorological Factors on Tiltmeter Interference Characteristics
摘要
Abstract
We use the Changshu seismic station water tube meter and vertical tilt data from the 2009~2015 observed pendulum,in relation to changes in the natural environment (air pressure,rainfall,temperature,temperature of the cave,etc.).The characteristics of these influences are analyzed,and the results show that:(1) rainfall interference on observation data is most significant for the NS component with south dipping and the EW component occurs with west dipping;the magnitude of the NS component interference is larger than that of the EW component;and the vertical pendulum interference is greater than that of water tube tiltmeter.(2) Pressure changes affect short cycle micro dynamic interference which leads to the daily value curve short time distortion.(3) The variation of the temperature and the temperature of the tunnel caused by the change of the observed value is obvious,but the effect of the observation value is not obvious.关键词
