Engineering Characteristics of Rock Masses
General
Engineering characteristics of rock masses are examined from the aspects of three general
conditions:
Fresh intact rock (competent rock) — Sections 5.2.3 through 5.2.5
●
Decomposed rock —
Section 6.7
●
Nonintact rock — Sections 6.3 through 6.6
●
Engineering properties in general for the three rock-mass conditions are summarized in
Table 5.15.
