摘要

对潜在问题区域(如空洞和不连续区域)进行现场表征和成像的快速方法在岩土工程中非常有价值，可以管理风险并实现业务目标。我们提出了一种近乎实时的筛选工具，该工具使用地震表面波属性(相速度和能量)来产生岩性变化和其他浅层目标的定量指示。我们给出了一个工程实验的结果，并将它们与现场的先验信息进行了比较。

Fast Near-Surface Investigation With Surface-Wave Attributes

Summary Fast methods for site characterization and imaging of potentially problematic zones, such as voids and discontinuities, are valuable in geotechnical engineering, to manage risks and meet business objectives. We present a nearly real-time screening tool which uses seismic surface-wave attributes (phase velocity and energy) to produce quantitative indication of lithological variations and other shallow targets. We present the results from an engineering experiment and compare them with a priori information on the site.
