单点地震技术在浅覆盖区区域地质调查中的应用研究
The Application of the Single-Receiver Seismics to Geological Survey in the Shallow Covered Areas
【摘要】 以阿龙山地区森林浅覆盖区 1:2 5万地质调查为基础 ,介绍了单点地震方法的仪器与数据采集及处理 ,并结合利用探槽和岩石露头所得的基岩地质剖面图 ,对比分析了两种方法的处理结果。单点地震技术具有野外数据采集速度快 ,使用检波器数量少 ,仪器轻便 ,实时观测地质体弹性波变化规律和无需复杂的数据处理等优点 ;与槽探调查相结合 ,可快速探测覆盖层厚度、基岩起伏形态、岩性接触带和接触关系
【Abstract】 Based on 1∶250 000 geological cartography in the forest shallow covered areas in Alongshan Mt.,the instruments and data acquisition and processing of single-receiver seismic methoded were used to detect the bedrock,corporating with the bedrock geological profile attained by taking advantage of tanks and rock crops. The single-receiver seismic technique is demonstrated to be quicker on the data acquisition in the field,and with less using geophones than other seismic methods.The instruments are potable,real-timely monitor of elastic waves variance, without complicated processing. Combined with tanks survey,this method can rapidly measure the thickness of covering layer,the status and characters of the bedrock.
