| Description: | Miscellaneous Paper Abstract: This report s ummarizes the compilation of a sizable data base of seismic velocities measured in situ with high-quality crosshole methods. The objective of developing the data base is to determine, eventually, the most accurate means of estimating dynamic shear modulus or shear wave velocity in soil given any number of known parameters. This data base may be useful in a number of Corps of Engineers applications including prediction of ground motions from nuclear or high-explosions, deployment of passive seismic arrays, employment of active seismic systems, and evaluation of dynamic response of facilities. Data were collected from several sources in private industry and state and Federal government agencies at sites located across the United States. Different types of projects, soils, geologic backgrounds , seismic zones, and ground-water conditions were used. Over 2,000 data points were collected in two distinct data bases that were developed for different approaches to correlations. Factors known to affect shear modulus or shear wave velocity and parameters used as independent correlative variables are discussed and presented in this report. Results of numerous previous correlative studies are used. Criteria used to select data are presented and justified. The distribution of data in the two data bases and ranges in shear wave velocity are summarized to characterize the nature of the data. Visual observations of preliminary correlations are made. |
