浅层地震探测的可控震源信号设计
|
摘要
在工程与环境物探中，浅层地震探测是一种常用的高分辨率物探方法，但是这种方法使用的炸药震源和枪击震源破坏力大，对人和建筑物都有危害，因而被禁止在人口稠密的地区使用．因此，无公害的电磁驱动可控震源技术得到了发展和应用．利用扫描信号压缩技术，小能量弹性波 Chirp 信号可持续向地下发送，不损害地面和建筑物，对人群也没有影响，是一种较理想的城市浅层地震震源．本文介绍了电磁驱动可控震源的信号设计方法，并简要介绍了具有波束定向能力的相控震源的设计思想．
Shallow seismic exploration is one of geophysical methods with high resolution.It is commonly used in en-gineering and environment survey.The explosion or popping sources,often used in shallow seismic exploration,arealmost forbidden within urban area because of their harmful effect on environment.In oder to solve this problem,thetechniques of Electrodynamic Vibroseis are developed.By sweep compression techniques,small elastic chirp signalscan be sent into the ground for a long time without any destruction of ground surface and harmful effect on humanbody and buildings.Vibroseis signal design method,beam—forming electrodynamic vibrator system and phased arrayprinciple are discussed in this paper.
