| Abstract: | Based on the observation data of SS-Y extensometer at Yixian Seismic Station from 2014 to 2021,five typical events disturbed by the environment are analyzed,combined with the tectonic stress background field of Yixian deformation cave and the quantitative calculation of the model. The following conclusions are obtained:(1) The load strain caused by the load interference source on the observation data of the extensometer at Yixian Station is related to the distance and load of the interference source and is positively correlated;(2) The SS-Y extensometer of Yixian Station is divided into three parts,where the NS test item and the NE test item are subjected to the abnormal amplitude of load disturbance curve.(3) The results of three-dimensional model simulation of interference sources are smaller than those of anomalous variables. |
