The computer analysis of bulging deformation in dry walls using software based on distinct element code is presented. The work is based on the simulation of results obtained from tests conducted on a series of large scale model walls. This work was undertaken as part of a research project to investigate the structural stability of dry-stone walls at Great Zimbabwe. The form of the physical model tests is briefly described and the general background to the distinct element as embodied in the UDEC software is given. The results of the computer simulations of three different walls are presented and compared with those obtained for the physical models. The influence of block size and void position is considered. Conclusions are drawn indicating the areas where the computer simulations successfully reproduced the behaviour of the physical models and the areas where they were deficient.
