多套地震仪器同步采集研究

Study on synchronous acquisition by multiple seismographs

多套仪器同步采集可使地震采集道数成倍增加,能解决单套仪器道容量不够的问题,而且还具有很大的灵活性和适用范围。本文通过"跨长江荆江段施工"一例,从另一个角度提出了在特殊地表条件下使用多套地震仪器同步采集的优势,即:在长江两岸各停放一套仪器采用两套仪器同步采集方式,比直接使用一套仪器具有的优势。并分析了一例不同步的故障,给出了相应的解决办法。

Synchronous acquisition by multiple seismographs can increase the seismic acquisition channels double and double, which can solve the issue of insufficient capacity of channels in single seismograph, and have big flexibility and adaptive range. Through the case of operation in Jingjiang part of Yangzi river, the paper presented the superiority of synchronous acquisition by using multiple seismographs in special surface conditions from other aspect, that is using two sets of seismographs for synchronous acquisition and setting a seismograph separately on both side of Yangzi river have superiority to using a set of seismograph. The paper analyzed the non-synchronous trouble in one case and gave corresponding solution .
