[1] Joint sets within sedimentary basins are commonly interpreted to have formed by tensile failure in conditions where pore fluid pressure was elevated. Such tensile fractures are inferred to be a part of the process that relieves high fluid pressure by locally increasing rock permeability. In spite of the importance of this feedback mechanism, the detailed mechanics of hydraulic fracture gene...

a series of tests and also numerical analyses were conducted to explore the mechanical behavior of a mixture of coarse gravelsize particles floating in a matrix of silt, sand or clay. the research is a step forward in an ongoing investigation on behavior of composite clay, which is used as the core material of some large embankment dams all over the world. after providing the reader with an ove...

Capturing the in-situ state of mine tailings is important in determining its behaviour under loading for evaluating risk failure dams. Obtaining a high-quality undisturbed sample through tube sampling thus great value to responsible engineer. However, process itself disturbs soil and changes state. Since driven by effective stress, one method evaluate disturbance induced during monitor soil’s p...
