水平摆与垂直摆倾斜仪观测资料干扰特征对比
|
摘要
对青海省格尔木、门源和乐都地震台水平摆与垂直摆倾斜仪观测资料进行对比分析,论述温度、气压、人为活动(工作人员进入观测山洞)以及大风等干扰因素对观测资料的不同影响,发现垂直摆倾斜仪受温度、大风和人为活动等因素的干扰程度总体低于水平摆倾斜仪,对观测环境的要求相对较低。
Through the analysis of contrast observation data of tiltmeters of Golmud, Menyuan and Ledu seismic stations in Qinghai Province, the interferences of temperature, atmospheric pressure, human activity in the observation hole chamber, and other interference factors such as strong winds are discussed in this paper, the impact of different interferences on observation data are compared. The results of this research show that the degree that the vertical pendulum tiltmeter be disturbed is less than that of the horizontal pendulum tiltmeter as a whole. The requirement of observation environment for vertical pendulum tiltmeter is also lower.
