This article sketches the recent conclusions and current activity of 3 selected research areas in geological engineering at Berkeley. These are: in-situ testing of rock deformability; computation of stresses and strains in rock around valleys and tunnels; and applications of rock noise to study of slope stability, fault activity, and rock deformation. In the first area, a bore hole, plate-bearing type testing device capable of applying pressures up to 10,000 psi and measuring rock displacements of 5 millionths inch at any depth in an NX (3-inch diameter) drill hole has been developed. In the area of stress analysis, finite element studies have been made to determine the effect of layered structures and contacts between unlike rock types on stress strain distribution about tunnels, boreholes, valleys, and surface cuttings. Rock noise research includes detection of noises in landslides, model studies of noise in soil slopes tilted to failure, study of rock noise in uniaxial and triaxial compression tests, and development of a recording station for continuous monitoring of possible noises from the San Andreas fault zone. /AUTHOR/
