承压水位观测井观测数据评价方法探讨
|
摘要
基于中国大陆363口地震承压水位观测井的时值观测数据,利用日均值拟合、NAKAI拟合和逐月潮汐参数计算,给出了反映观测井内在质量的9个特征参数,介绍了特征参数的动态特征。将特征参数从优到劣划分为A、B、C、D、E五个级别,给出了各级别的限差指标。
The observed data of 363 wells belong to China water level net for earthquake monitoring are collected and analyzed one by one.9 parameters determinated by the day average value fitting,NAKAI fitting and monthly tidal factor are used to quantify the observed data.On the basis of these results,the general standard parameters of the observation of these water wells are given.The five levels(A,B,C,D,and E) are defined according to the statistic results.The estimation results for each well are also calculated.The results could be referred by construction of well water level and the users of the data.
