摘要
区域精密水准测量在地震监测中发挥了重要的作用,但是由于其作业范围广、观测周期长,容易受外界复杂多变的环境因素影响。目前对环境因素的影响分析大多是定性描述,缺乏实验观测数据的支撑。针对这一问题,选取大约2000km区域精密水准观测数据,结合观测环境资料,统计分析不同环境因素对观测成果的影响程度,并提出了相应的改进措施。
Regional precise leveling plays an important role in earthquake monitoring, but for its wide working range and long observation period, it is easy to be influenced by the complex and changeable environment. At present, the analysis of environmental factors mainly based on qualitatively description, and lack of experimental observation data support. To solve this problem, about 2000km regional precise leveling data were chosen, and combined with the observation data, statistical analysis of different environmental factors of impact on the observation results, and puts forward the corresponding improvement measures.
