Introduction - Rock Mechanics Based on an Anisotropic Jointed Rock Model - page 1

1 Introduction

This topic focuses on the fundamentals of rock mechanics as a basis for the safe and
economical design and construction of tunnels, dam foundations and slopes in joint-
ed and anisotropic rock. It is divided into four main parts:
A Fundamentals and models
B Analysis and design methods

C Exploration, testing and monitoring
D Applications and case histories.
The rock mechanical models presented account for the influence of discontinuities
on the stress-strain behavior and the permeability of jointed rock masses. They are
implemented in three-dimensional finite element analysis methods, which enable a re-
alistic simulation of the load-carrying behavior of structures in rock. Also, advanced
methods to describe squeezing, swelling and creeping rock masses are implemented.
The corresponding computer programs developed and applied by the author and his
colleagues will soon be available for sale.
In comparison to the rock mechanics topic irst published by the author in German
in 1984 (Wittke 1984), this topic has been completely revised and is now based on
more than 40 years of experience in the design and construction of tunnels, dams and
slopes in many kinds of rock.
The topic is aimed at students taking advanced courses in geotechnics and rock me-
chanics, at postgraduate students (PhD) and at researchers as an introduction, as well
as at civil engineers working as consultants, planners and designers, or in the con-
struction industry and within public authorities. The required academic background
for readers is a graduate degree (BEng or BSc) in civil engineering. However, inter-
disciplinary working professionals coming from geology, mining and natural sciences
can also beneit from this topic.
The practical examples and case histories presented in this topic should facilitate the
consideration of rock mechanics in the reader's own work.
