摘要

在中国地震局实施的首都圈防震减灾示范区系统工程中,河北地区安装了21台套水位数字记录仪,并于2001年10月1日开始与模拟观测并行运转。与模拟观测相比,数字化观测具有数据信息量大,传输速度快,人为误差小的优点,从而增加了水位高频、短周期的信息量,为捕捉地震短临异常信息提供了有利条件。通过对河北地区数字化观测与模拟观测进行对比分析认为,静水位井的数字化观测与模拟观测资料变化特征一致。并着重讨论以往用于模拟观测时值资料分析处理方法在数字化水位观测资料中的应用。
There are 21 sets of digitized record instruments of underground water level in Hebei Province. Digitized observation of underground water level has been carried on together with the traditional simulated observation since 10/01/2001. Compared with the traditional simulated observation, digitized observation has the advantages of rapid data transmission, larger amount of information and less manmade error. It will greatly increase the high frequency and short period information of underground water level, and improve significantly our ability to catch shortterm and imminent precursory anomalies. The results of comparative analysis show that the data variation characteristics of digitized observation are identical to those of simulated observation. In this paper, we mainly discuss some methods′application on the data of digitized observation, which is a series of hourly value analysis methods used in simulated observation before.
