IN SITU MEASUREMENT OF SOIL PROPERTIES
This report presents evaluation of five in situ testing devices. The five devices are Iowa Borehole Shear Device, Vane Shear Device, Standard Penetrometer, Dutch Cone Penetrometer and Cambridge Self Boring Pressuremeter. These devices have been field tested in three northern California sites, namely: Downtown Sacramento, Rio Vista, and Mare Island. The in situ tests were conducted in silty sand, silty clay, San Francisco bay mud (recent), peat, and peaty clay. Maximum depth tested was 50 feet (approximately 16 m). Laboratory tests were conducted on undisturbed samples. The various soil parameters derived from laboratory tests have been compared with those from the field tests. The effects of soil disturbance are discussed. A separate report appendix intended for limited distribution (upon request) contains information on modification of probes, adaptation of drill rigs, calibration, testing procedures, boring profiles, and a bibliography.
