摘要
地震方法是调查深埋断层的主要手段 ,在闹市区 ,表层地震地质条件的复杂性和人文活动的频繁性 ,使得地震方法的应用受到了很大限制。在适当的工作时间 ,采用相关和水平叠加技术、使用较高频率的检波器和滤波器 ,并采取一些其它的数据采集技术和相应的数据处理技术 ,有利于压制强背景干扰 ,提高地震记录的信噪比和分辨率 。
Seismic methods are main tool of imvestigating deep buried active faults. Applications of seismic method are restricted seriously due to complex of shallow seismic geological conditions and frequency of artificial activity in the city. It is favorable for suppressing strong background noise and improving S/N ratio and resolution of seismic record when high frequency geophones and phase correlating stacking techniques as well as some other techniques at suitable working time are used during field data acquisition. We can obtain high quality seismic section when proper data processing techniques are used at data processing stage.
