【摘要】 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。更多还原

【Abstract】 The paper analyzed the difference of level observation variation velocity in Hutubi cave and annual variation velocity of fault-crossing level observation result using two period fixed point level observation data of observation cave in Hutubi seismic station and four period fault-crossing observation data in Hutubi in the same time,level observation data of Dafeng survey ling from 1987 to2012 so as to judge the reliability of Ni004 optical level used in Hutubi seismic station and put forward some reasonable suggestion according to the analysis result. Furthermore,we studied the crustal deformation characteristic in the study area according to the contrast analysis result.更多还原
