Coal body is a type of fractured rock mass in which lots of cleat fractures developed. Its mechanical properties vary with the parametric variation of coal rock block, face cleat and butt cleat. Based on the linear elastic theory and displacement equivalent principle and simplifying the face cleat and butt cleat as multi-bank penetrating and intermittent cracks, the model was established to cal...

The city bypass tunnel of Waidhofen an der Ybbs (Austria) is situated in an intricate geological-geotechnical complex consisting of soil, hard soil, weak rock and solid rock. Marls and marly limestone (Waidhofener formation) predominate followed by tectonic breccia of the Alpine cliff zone, which is a tectonic melange zone. Materials of this kind universally have isolated interior blocks embedd...

In this paper, conceptual models are presented to identify the effects of solid deformation on the changes in rock permeabilities for (a) fractured media, (b) intact media, and (c) fractured porous media subjected to external loads, all in steady state conditions. Finite element schemes are then developed with embedded correlations between induced strain and modified permeability to simulate th...

The organization of the actin cytoskeleton plays a key role in regulating cell mechanics. It is fundamentally altered during transformation, affecting how cells interact with their environment. We investigated mechanical properties of cells expressing constitutively active, oncogenic Ras (RasV12) in adherent and suspended states. To do this, we utilized atomic force microscopy and a microfluidi...

ABSTRACT: The authors have proposed and discussed temporary storage of heated water in openings excavated in rock mountain from the viewpoints of multiple-utilization of land, environmental safeguards, energy conservation, etc. When used for heated-water storage, the rock mass around the openings will receive the effects of the heated water. In this study, a uniaxial compression creep test at h...
