Book Synopsis Material Properties for Postshot Mixed Company Analysis: Recommendations Based on Recent Laboratory and in Situ Test Data by : John Q. Ehrgott

Download or read book Material Properties for Postshot Mixed Company Analysis: Recommendations Based on Recent Laboratory and in Situ Test Data written by John Q. Ehrgott. This book was released on 1974. Available in PDF, EPUB and Kindle. Book excerpt: The paper presents the results of a reevaluation of the Mixed Company site profile and constitutive properties using both field and laboratory data. Revisions to the subsurface profile were based primarily on the water contents determined in the soil overburden at shot time. An extensive reanalysis of the seismic velocity data was conducted. New constitutive property recommendations for the overburden soil were developed based on laboratory tests conducted on specimens taken in the field just a few days after the event. The properties of the Kayenta Formation were revised to consider the effect of loading rate on the initial portion of the uniaxial strain (UX) test stress-strain curves, the effects of anisotropy on the observed triaxial shear (TX) and UX test behaviors, and the correlation observed between shear strength obtained from laboratory tests and strength obtained from an in situ test.
