摘要
张家口地震监测中心站定点形变测项迁至崇礼形变观测山洞,选取2020年1月—2024年3月地倾斜、洞体应变、钻孔应变等观测资料,从台址条件、仪器设备运行稳定性、干扰因素、观测质量精度等方面进行综合分析与评价。分析认为:观测资料连续、稳定、可靠,固体潮汐观测精度指标优于国内定点形变Ⅰ类台标准,与国内同类先进台站相媲美,尤其是DSQ型水管倾斜仪,其观测资料质量达国内领先水平。
This paper comprehensively analyzes and evaluates the quality of observation data from January 2020 to March 2024 for fixed-point deformation measurement items such as ground tilt,cavern strain,and borehole strain in the newly relocated Chongli deformation observation cavern at Zhangjiakou Central Station,from the aspects of site conditions,operational stability of instruments and equipment,interference factors,and observation quality and accuracy.The analysis shows that the observation data are continuous,stable,and reliable,and the accuracy index of solid tide observation is superior to the standard of domestic Class I fixed-point deformation stations,comparable to similar advanced domestic stations,especially the DSQ water tube tiltmeter observation,which has reached the leading domestic level.
