Design Analysis in Rock Mechanics

As the confining pressure is increased, the rapid decline in load carrying capacity after the peak load is reached becomes less striking until, after a mean pressure known as the brittle-to-ductile transition pressure, the rock behaves in a near plastic manner. In most cases, however, it is the effect of pore water pressure that exerts the greatest influence on rock strength.

If drainage is impeded during loading, the pores or fissures will compress the contained water, raising its pressure. Creep — strain continues when the applied stress is held constant. Relaxation — a decrease in strain occurs when the applied stress is held constant.

Fatigue — an increase in strain occurs due to cyclic changes in stress. The limited test data does show though, that increasing temperatures reduces the elastic modulus and compressive strength, whilst increasing the ductility in the post-peak region.

Building on the history of material testing, it was natural to express the strength of a material in terms of the stress present in the test specimen at failure i.

A tension cutoff has been introduced to the Mohr-Coulomb criterion to predict the proper orientation of the failure plane in tension. They can be considered linear only over limited ranges of confining pressures.

For Underground Mining

Despite these difficulties, the Mohr-Coulomb failure criterion remains one of the most commonly applied failure criterion, and is especially significant and valid for discontinuities and discontinuous rock masses. Since this is one of the few techniques available for estimating in situ rock mass strength from geological data, the criterion has become widely used in rock mechanics analysis.

Discontinuities have been introduced into the rock by geological events, at different times and as a result of different stress states. Very often, the process by which a discontinuity has been formed may have implications for its geometrical and mechanical properties. Very often major discontinuities delineate blocks within the rock mass, and within these blocks there is a further suite of discontinuities.

Thus, we might expect that a relation of the form: should exist.

There is, however, no standardized method of measuring and characterizing rock structure geometry, because the emphasis and accuracy with which the separate parameters are specified will depend on the engineering objectives. Frequency i. An important feature for engineering is the overall quality of the rock mass cut by these superimposed fracture systems.

For this reason, the concept of the RQD was developed. It is often useful to present this data in a graphical form to aid visualization and engineering analysis. It must be remembered though, that it may be difficult to distinguish which set a particular discontinuity belongs to or that in some cases a single discontinuity may be the controlling factor as opposed to a set of discontinuities. In practice, the persistence is almost always measured by the one dimensional extent of the trace lengths as exposed on rock faces.

This obviously introduces a degree of sampling bias that must be accounted for in the interpretation of results.
