Abstract: Rock engineering is an age old craft and has been used since the dawn of civilisation. Classification systems, theoretical calculations, site investigation and numerical simulations are the many approaches used in rock engineering. However, because of its accuracy and the progress of computer technology, numerical simulations have become the method of choice. However, typical rock masses are rarely continuous in nature; irregularities in the form of faults, joints or bedding plates do occur. Interpreting these discontinuities has proven to be quite the task in numerical simulation. Furthermore, representing a rock mass with these discontinuities as a computer model has also offered some challenge. As Discontinuous Deformation Analysis (DDA) is able to provide us with a dependable model and is able to competently represent the mechanical behaviour of rock materials under various loading. It is the method used most commonly today and will be used in this report. The aim of this report is to understand the deformation behaviour of rock under different loading conditions and with different joint orientation. Literature reviews on rock mass and numerical modeling will be carried out first, followed by a preamble on Discontinuous Deformation Analysis (DDA). 9 cases about loading in an underground cavern will be simulated and the effect on varying the loading on the deformation will be discussed.
