| 摘 要： | 山区地形复杂,浅层地震地质条件变化较大,成孔形式不一,数据采集困难。通过对岩石出露区、坡积物堆积区及黄土覆盖区进行试验分析,采用了封孔、压孔、组合炮及特殊观测系统等手段,有效地压制了干扰,提高了信噪比,使目的层反射波明显,得到了较理想的野外原始数据。

| Abstract: | Relief in mountainous region is complicated,shallow seismic geological condition is varied;borehole form differs;data gathering difficult.Through testings and analyses in rocky area,talus area and loess covered area,means of borehole sealing,killing,multiple shot arrays and special field setup were used,effectively suppressed noise and improved signal to noise ratio,made the reflection wave from target clearer,rather perfect field data thus obtained. |
