中文摘要:
      面波法与折射波法地震勘探能够获得岩体的横波速度和纵波速度,而且可采用同一地震仪器完成.本文主要阐述面波法频散曲线的分层拟合对整个地层进行速度分层,确定覆盖层、风化层的厚度以及基岩层界面,并与折射渡法相结合计算出基岩层的弹性力学指标.此外,对单一采用面波法计算弹性力学指标进行了探讨.
英文摘要:
      S -wave and P -wave velocity of terrane can be obtained with surface - wave survey and refactive - wave survey. They can be accomplished by only using a seismograph. The paper describes how distinguish velocity layer by frequency scatterring curve fitting method to determine thickness of overburden layer and weathered layer and base - rock interface. Elastic parameter can be calculated by combing refractive - wave survey. In addition, the paper presents also method of calculating elastic parameter with single surface - wave survey.
