Verification of subsurface conditions at selected ''rock'' accelerograph stations in California. Volume 2

Technical Report ·
OSTI ID:5010252
This report investigates the subsurface soil conditions at accelerograph stations which have been categorized by other researchers as ''rock'' sites. Contained in this volume are findings of the site conditions at 29 accelerograph stations in California. Subsurface conditions at the sites were investigated with a geologic reconnaissance and a review of available boring data. At three sites, where boring data was not available, a test hole was drilled to better define the depth to rock. Of the 29 ''rock'' sites that were investigated, less than half could be verified as being founded on or within about 20 feet of rock. This would imply that over half of the stations are really soil sites.
