• Introduction. Theory of DDA. Three Dimensional DDA. Geological Input Parameters for Realistic DDA Modeling. DDA Verification and Validation. DDA in Rock Tunneling Engineering. DDA in Rock Slope Engineering. Current Trends and Future Developments. Appendix: Manual for DDA Programs. Program DDA LINE (DL). Program DDA CUT (DC). Program DDA FORWARD (DF).

"This book brings the extraordinary power of DDA (Discontinuous Deformation Analysis) to the tool-baskets of engineers who are responsible for excavations and foundations in jointed and faulted rock masses. The mathematical basis for DDA originated in the brilliant PhD Dissertation and subsequent publications of Gen-hua Shi, and has been furthered by many applications in recent years. These include Professor Hatzor’s resourceful analyses of works needed to protect ancient surficial and underground structures in Israel. Important developments have been published in the proceedings of the International Assoc. for Computer Methods and Advances in Geomechanics, and in other recent engineering literature. With this book, the potential applications of DDA will be further recognized and applied for the benefit of the entire engineering community."Professor Richard E. Goodman, Professor Emeritus at the department of Civil and Environmental Engineering, University of California, Berkeley.
