Finite element for rock joints and interfaces
International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1973The objective of this paper is to present a method for dynamic stress analysis of saturated soil structures subjected to earthquake loading. The soil is idealized as a fluid saturated porous solid. The coupled equations of motion of the finite element discretized system are solved by a step-by-step integration scheme to determine the motion of the ...

Mechanics of Jointing in Rocks
Geological Magazine, 1959AbstractThe current theories dealing with the mechanics of joint development are discussed critically. An analysis of the stress conditions which can exist in competent rocks in the crust is presented. The conclusion is reached that “Master” and “Regional” Joints can be, generically, either “tensional” or “shear” structures.

Implications of Joint Properties on the Strength of a Jointed Rock Mass
Advances in Unsaturated Soil, Geo-Hazard, and Geo-Environmental Engineering, 2011In order to minimize the environmental and physical hazards of rock slope failures in deep open cut mines, evaluation of rock mass strength with a reasonable degree of accuracy is required. The task is made much more difficult due to the presence of discontinuities or joints, as the strength of a rock mass depends on both the strength of intact rock ...

Effect of Joint Geometry and Transmissivity on Jointed Rock Hydraulics
Journal of Engineering Mechanics, 1999The effect of joint geometry parameters (joint orientation, joint density, and joint size) and joint transmissivity on the hydraulic properties of jointed rock blocks was examined in two dimensions using joint networks with two joint sets through numerical experiments.

Rock joints — BEM computations
1995Publisher Summary This chapter discusses the boundary element methods that allow the modeling of a continuum, which contains joints and faults. The two main methods of analysis described are the displacement discontinuity method and the multiregion boundary element method.

This report discusses several constitutive models for joint behavior with emphasis upon the experimental data which motivates them. Particular emphasis is placed upon data available for granite. The LDEC joint model is presented in detail and LDEC simulations using this model are compared against data from constant normal stiffness and constant normal ...
