... ground conditions. To mitigate such risks, countermeasures against earthquakes may be used where there are severe conditions such as faults, fracture zones, portals or extremely shallow areas, however, their mechanisms and effects are not fully understood. In this study, static loading tests were carried...

... of in-situ loading tests, i.e. the Plate Loading Test, the Flat Jack Test, the Radial Jacking Test, the Water Chamber Test, the borehole loading test and so on. The in-situ tests are presently employed in major rock engineering projects, to provide more rational data for design of rock structures which...

... (1975) [1] showed that the peak strength obtained in multiple-step loading tests using this point is negligibly different from that obtained by single-step tests. These results justified the use of this criterion in a number of studies. However, there is no doubt that this point is not easily...
