... of the dam, in-situ borehole testing, down-the-hole geophysics, and core drilling was carried out to supplement limited construction, historic drilling and instrumentation records. The rock mass strength parameters and the shear strengths on large undulating through-going discontinuities, were based...

... have been performed to establish the brittle-toductile transition. Based on the results of the tests, it is shown that the brittle-to-ductile transition can be related to the over-consolidation ratio. A relationship between normalized undrained shear strength and over-consolidation ratio is established...

..., there is considerable strength gain over a smooth test pair. The addition of lateral constraints further increases test sample shear strength in the 3-D case, because the block is forced to dilate upward when it would prefer to dilate laterally. In this paper, we examine this strength gain as experienced...
