摘要

在简要介绍城市浅层地震勘探干扰波特点的基础上 ,结合福州市活断层探测的浅层地震试验探测资料 ,阐述了抗干扰高分辨率浅层地震勘探的技术装备、地震数据采集的技术方法以及在强干扰背景条件下围绕抗干扰和提高地震资料信噪比与分辨率而采取的技术措施。试验结果表明 :采用可控震源和与其相匹配的地震仪器以及小道间距、小偏移距、多通道和高频检波器接收的工作方法 ,是实现抗干扰高分辨率浅层地震数据采集的有效途径。
In addition to a brief account of characteristics of disturbing waves in urban shallow seismic exploration, an exposition of technical facilities and seismic data acquisition techniques for anti-jamming and high-resolution shallow seismic exploration is given in this paper on the basis of shallow seismic experimental data of active fault surveying in Fuzhou City. The technical measures taken for anti-jamming, improving signal to noise ratio and resolution of seismic data are expounded as well. The experiment shows that the effective approach to accomplishing anti-jamming, high-resolution shallow seismic data acquisition is receiving with mini trace intervals, mini offsets, multi-channel and high-frequency Geophones by using mini-vibrator and the matched seismograph.
