Rock Borehole Shear Test

Two obstacles to a more widespread application of rock mechanics for design of underground structures are: 1) difficulties in measuring in situ stress, and 2) problems in determining the rock strength in response to present and anticipated stresses. A project was initiated at Iowa State University in 1970 to develop a new test device and method to quickly evaluate rock shearing strength in situ and under various controlled normal stresses. For this purpose, it was proposed to adapt the principle of the Iowa Borehole Shear soil testing device.
