Rock engineering as well as rock mechanics is a truly
interdisciplinary subject, with applications in geology and geophysics, mining,
petroleum, and civil engineering. It relates to energy recovery and development,
construction of underground spaces for transportation, water resources and
defense facilities, prediction of earthquakes, and many other activities of
greatest importance.
Practitioners in this field have made important contributions in
mining and civil engineering possible by accumulated practical experience,
engineering judgment and often by a trial-and-error approach. In essence, the
rock engineering practice has traditionally been an art rather than an
engineering science. Despite this fact, the rock engineering science has been
advanced by the devoted efforts of many scientist, researchers and
engineers.
Today, many workers in the rock engineering field tend to use
comprehensive numerical modeling to study and solve complex issues. Although
these models are powerful, it is difficult and rather impossible to obtain the
necessary input data. It should be emphasized that field observations and
measurements could play an important role in solving the issues. It has been
pointed out that there is a big gap between theories and
practice.
