利用呼图壁地震台洞体场地水准二期的比对观测数据、呼图壁场地跨断层水准四期的同时间段观测资料以及1987~2012年大丰跨断层测线的水准观测数据,分析了呼图壁红山地震台洞体场地水准观测成果的变化速率与跨断层水准观测成果的年变速率的差异性,判定原地震台使用的Ni004光学水准仪的可靠性,依据分析结果提出合理建议。并根据大丰跨断层水准观测的历史观测成果和呼图壁洞体场地水准观测比对后的分析结果,初步探索研究跨断层水准在研究区域的地形变特征。
By using the comparison data of the second stage of Hutub Wall Seismic Station and the observation data of the same period of the fourth section of Hutubi site and the observation data of Dafeng’s cross-fault line survey from 1987 to 2012, According to the difference between the rate of change of leveling observation results and the annual change rate of cross-fault leveling observation results, the reliability of the Ni004 optical level instrument used by the original seismic station is determined, and reasonable suggestions are put forward based on the analysis results . Based on the historical observation results of the Dafeng-crossing fault leveling observation and the site-level comparison and analysis of the Hutubi cave bodywork, preliminary study is made on the characteristics of the terrain deformation of the cross-fault leveling in the study area.
