CHARACTERISTICS OF REPEATED MEASUREMENT DATA OF SHORT-LINE LEVELING IN TANGSHAN STATION
-
摘要: 整理唐山台2003-2010年的水准复测记录,初步分析其月频次统计特征,比较水准4个测段及不分测段的水准复测时间统计特征,发现在7月份月复测频次最少,在1、3月份水准复测频次最高。进而计算不分测段的水准复测序列与台站记录的气温月均值、降雨月累积降雨量及区域小震月频次序列的相关性,结果发现:台站水准复测月累积频次与气温和降雨并无显著的相关性,而和区域地震活动频次有某种关联。Abstract: Based on the preliminary analysis of short-line leveling repeated measurement data collected from 2003 to 2010, its monthly frequencies are calculated and compared by different short-line leveling segments, which show that the frequency is less in July and that is more in January and March.Then the repeated measurement data series are combined with the air temperature, cumulated monthly precipitation and the monthly earthquake frequencies to get the correlation.And the result shows that there is no clear correlation between frequency of the shortline leveling repeated measurement and air temperature or precipitation, but some connection between the short-line leveling repeated measurement and regional seismicity.
