摘　　要：GNSS观测技术经过多年的发展,已在地壳形变、大地测量、地震预报分析等领域得到了广泛的应用。为验证10米深的土层点与基岩点对观测数据的影响,简要介绍了辽宁省地震局新建GNSS连续观测站观测墩及防雷设施土建过程,对2020年数据解算与陆态网络GNSS数据对比,分析其稳定性;利用TEQC软件对2020年的原始数据进行质量检测,结合建设勘选资料与实地考察情况,分析影响数据质量的因素,从而完善建设方案,为今后GNSS观测站的建设以及数据质量检验方法提供技术支撑。After years of development,GNSS observation technology has been widely used in the fields of crustal deformation,geodesy,earthquake prediction and analysis.In order to verify the impact of 10m deep soil points and bedrock points on the observation data,this article briefly introduces the construction pro⁃cess of the observation piers and lightning protection facilities of the newly built GNSS continuous observa⁃tion station of the Liaoning Seismological Bureau,and calculates the 2020 data and China's Mainland Con⁃struct environmental monitoring network GNSS data comparison and analyze its stability;and use TEQC software to conduct quality inspection on the original data in 2020,combine the construction survey data and field inspections,analyze the factors that affect the data quality,and improve the construction plan.In the future,the construction of GNSS observing stations and data quality inspection methods will provide technical support.
