Although in situ tests have the advantage of involving a large volume or rock tested under the same environmental conditions as are prevailing in the rock mass, such tests are expensive and time consuming. In addition, there are a number of controversial questions pertinent to in situ tests. This presentation discusses the first-hand experience with three in situ test methods. These are: (i) plate bearing tests, (ii) large and small flat jack tests, and (iii) Goodman jack tests. By identifying the problems associated with in situ testing, useful lessons can be learned for large scale laboratory testing in geomechanics.
