Abstract:

The report presents information on selected stress and modulus gages designed to measure the deformation of a small hole drilled into rock, and the applied pressure in the case of modulus gages. The gages selected were the USBM Borehole Deformation Gage, the CSIR Doorstopper, and the Photoelastic Stressmeter Glass Plug to measure stresses the Goodman Jack, the USBM cylindrical Pressure Cell, the Menard Pressuremeter and the Borehole Dilatometer Rocha to measure rock modulus values. The information was gathered, initially by questionnaire and in greater depth by personal communication, from engineers who have used the instruments in the field. Information is provided on the use, cost, time, and other factors relating to the selected gages. The information is oriented towards comparative selection of gages to be used in specific applications. Information on problems likely to be encountered in the field is given.
