Conceptual models for the stress-strain behaviour and permeability of a rock mass were developed in Parts A to C of the book. Procedures to investigate the stability of engineering structures in or on a rock mass were presented, these being based on the conceptual models. The capabilities of the procedures were demonstrated in examples. Part D subsequently described methods of investigation to determine the mechanical characteristics and permeability of a rock mass.
