Abstract:: The pre-processing analysis of 20 groups of seismic data in Taiwan in recent years is carried out to extract the VS vertical pendulum monitoring data in the coseismic area of Shaoguan Station. By comparing the curve shape anomalies of the VS vertical pendulum caused by the earthquake,the seismic reflection performance of the VS vertical pendulum at Shaoguan Station is analyzed. The sample point mixing function difference method was used to simulate the step-magnitude-magnitude curve of the vertical pendulum tiltmeter at Shaoguan Station,and the critical value of the induced step jump is solved. The paper performed linear difference processing on the amplitude-magnitude curve of the Shaoguan Station and Xinyi Station,analyzed the influence of the distance on the jump amplitude,and used the least squares method to process the differential data to solve the most or similar value of the difference data,that is the influence coefficient of the distance from the head to the order jump.
