Strength, Deformation and Friction of in situ Rock

Abstract

A field and laboratory program was conducted at several test sites to determine the strength, deformation, and frictional properties of a variety of rock types (sandstone, amphibolite, quartz diorite). The test results at Auburn and Glen Canyon dams compared favorably with those obtained by the US Bureau of Reclamation. A series of in situ and laboratory specimens from the MIXED COMPANY site were tested to determine the effects of specimen size, saturation, and anisotropy on the strength and deformation of massive sandstone. Direct and proportional shear tests were conducted to determine the effect of load path on frictional properties.
