Abstract

A shallow seismic reflection experiment was performed on a construction site to determine the feasibility of using reflection seismology to investigate the shallow structure in a weathered sand-gravel interlayered zone that was known to be a poor transmission of high-frequency seismic energy. Field-recording parameters were designed to fit the limited space of the urban construction survey area. The results show that the techniques employed in this experiment may resolve the structure of a site with poor reflection quality. An f-k dip filtering and deconvolution were necessary in processing the reflection data to eliminate various types of unwanted energy. The seismic interpretations in this study were verified by drilling and by a nearby excavation. -from Author
