... ABSTRACT Automated rock slope monitoring system has been established and the characteristics of slope behavior is analyzed with consideration of field rock structure by virtue of borehole information of joint orientations and positions acquired from Discontinuity Orientation Measurement (DOM...

... the shaking, with some relatively minor rockfalls at the top of the cliffs. The above is a substantial result of a full-scale experiment on the real rock structure. Therefore, a fundamental test of any model of this structure is that it must essentially duplicate the above experiment . As shown...

... be argued that the release, removal or control of stress concentrations around an excavation is of prime importance for the stability of rock structures in, for example, deep mining. The stress level at which a structure becomes unstable depends on the structural geometry and size, and may be governed...
