摘要
观测环境对水准测量的精度具有很大的影响,本文根据数字水准仪观测的自动记录特点,设计了振动对水准测量成果影响的实验。实验结果进一步证实了《地震台站观测环境技术要求(第3部分:地形变台站)》(GB/T19531.3—2004)和《地震水准测量规范》(DB/T5—2015)关于距铁路50 m以内不应选定埋设水准点的规定,为水准测量中点位选择提供了实验依据。
The observation environment has a great influence on the accuracy of leveling. According to the automatic recording characteristics of digital level observation the experiment of vibration influence on leveling results has been designed. The experimental results further confirmed the ＂environmental technical requirements of seismic station observation（ third parts： crustal deformation stations（ GB/T19531.3-2004）） ＂and＂earthquake leveling standard＂（ DB/T5-2015） provisions from the railway should not be selected within 50 meters embedded benchmarks. And it has provided experimental basis for the relevant requirements of leveling point selection.
