摘要
统计2008—2011年全国干扰不明显的垂直摆仪器资料,分析覆盖层的厚度、岩性对仪器精度的影响以及土建成本,结果表明,并非覆盖层越厚仪器精度越高,在岩性好的地区,覆盖层无需达到40 m厚度,可节约成本,且前兆台网布局更加合理。
Statistics of national did not significantly interfere with the vertical pendulum apparatus from 2008 to 2011data, analysis of cover layer thickness, lithology of instrument accuracy, as well as the construction cost analysis, the results show that, not covering layer is thick in- strument precision is high, the lithology of good parts, covering layer does not need to reach the 40 m thickness, which can not only save cost and can make a precursory network layout more reasonable. The station can choose to provide reference.
