项目摘要
To develop a new prospecting method, a series of fundamental study on the seismic wave attenuation in earth material is performed.1. A new method to evaluate the quality factor Q of earth material is proposed and the values of Q are estimated by using this method in in-situ.2. The extentional procedures of Hales's method for the case of irregular ground surface and multi-layers are discussed and it is proved that these procedures can be applied to the irregular ground surface and multi-layers problem.3. A numerical method to analyse the wave propagation and/or the dynamic stress field in constant Q medium is developed and some numerical results by this method are shown.
为了开发一种新的勘探方法,开展了一系列关于地震波在大地材料中衰减的基础性研究。提出了一种估算土料品质因数Q的新方法,并利用该方法对现场Q值进行了估算。讨论了Hales方法在不规则地表和多层情况下的推广过程,证明了这些方法可以应用于不规则地表和多层问题。本文提出了一种分析常Q介质中波的传播和/或动应力场的数值方法,并给出了用该方法得到的一些数值结果。
