Description: Technical Report
Abstract: This report presents a series of geophysical studies performed to determine the material characteristics of the foundation rock beneath the concrete gravity sections of Folsom Dam, California. The geophysical investigations were conducted to measure the values of compression- and shear-wave (P- and S-wave) propagation velocities as well as density of the foundation materials. The U.S. Army Engineer District, Sacramento, and the U.S. Army Engineer Research and Development Center agreed upon a finalized test program consisting of seismic crosshole testing and sonic and gamma-gamma logging. These measurements are used to compute rock property information for a dynamic analysis of the dam and its foundation. The field investigations and corresponding findings are described in this report.
