调整形变观测思路探寻地震预报的新途径

Adjust Deformdtion Observational Way to Explore New Path of Earthquake Forecasting

应用现有的仪器设备和技术手段,避开各种干扰因素捕捉新的观测要素,为地震预报提供可靠的前兆信息,本文提出了一种新的观测方案。新方案由三部分构成:一是在观测思路上将作用力作为观测目标;二是在台站的布局中改变现行的独立观测方式,以局域台站组的形式来集中布设观测点;三是对形变仪中的水管仪和伸缩仪布设方式进行调整,由单分量方向线上的相对观测改为两套仪器就同一固定点进行绝对值观测。

Using present deformation monitoring equipments and technique means,in order to avoid various interference factors and provide reliable precursor information for earthquake forecasting,a new way for deformation monitoring is presented in this paper.The new method consists of three parts,the first is to take acting force as deformation observation aim;the second is to changes spotting way of seismic station from independent observation in each station to station group concentrating observation;the third is to adjust spotting way of the FSQ water tube tilt-meter and SSY quatz tilt-meter from relative observation in single direction to absolute observation for same point using both equipments.
