Seismic Site Characterization through the Passive Surface Wave Survey
The passive surface wave survey method provides a non-invasive seismic site exploration approach for civil engineers. It works through measuring either human activity-induced ground vibrations or background ambient noise. It is superior to conventional geotechnical field testing approaches for site characterization over a large area. This paper reports surface wave survey case studies to demonstrate the application of this method to characterize local sites. Passive surface wave surveys were implemented in this research by collecting microtremors with designed sensor arrays. Measurements were processed to obtain the soil shear wave velocity profiles of the sites. Testing results were compared with borehole exploration data, which validated the passive surface wave survey measurements. Instrumentation, field testing design, and data analysis of this method were discussed. The paper envisages a great potential of the passive surface wave survey method in earthquake and geotechnical engineering applications in the urban environment.
