Equivalent elastic moduli of a rock mass consisting of orthorhombic layers

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1982
Abstract A stratified rock mass is considered to consist of a series of parallel layers each of which has orthorhombic elastic properties. When the thicknesses and properties of the layers vary with depth in either a random or systematic repeated fashion it is shown that the layered rock mass can be represented by an ‘equivalent’ homogeneous ...

Reliability analysis of tunnel roof in layered Hoek-Brown rock masses

Computers and Geotechnics, 2018
Abstract This paper develops a two-layer model and upper bound solutions for the shape of collapse block in rectangular tunnel subjected to seepage pressure, and then the reliability-based analysis is performed. According to the layered Hoek-Brown rock masses with different characteristics, a continuous failure mechanism of roof collapse in the deep ...

ACOUSTIC VELOCITY IN LAYERED ROCK MASSES WITH PERIODIC FRACTURES

2013
Fractures and layering in rock masses have a large impact on both the mechanical and hydraulic properties of the rock mass. When considering seismic elastic waves, fractures can also trap and guide waves and the behavior of such waves may prove useful for probing the geometrical and mechanical properties of the fractures. In the long- wavelength limit,

Bearing capacity of foundation on rock mass with weak layer

1995
This paper deals with a strip surface footing on a rock mass with a weak layer. The calculations of the bearing capacity were performed simultaneously by two computer programs using the finite element method and the finite difference method with independent development of the models.
