Our staff are experts in developing numerical models that capture the physical phenomena that control the behavior of the construction of underground structures.
One of our specialties is the development of detailed 2D & 3D numerical models to simulate the construction of sub-surface projects. Our modeling captures the dominant physical phenomena that control the behavior of underground construction. Our modeling encompasses the wide range of geotechnical challenges from slope stability assessments to in-depth structural assessments of the loads and internal forces acting on undergound openings ranging from squeezing, swelling to rock bursting in high stress ductile environments. Our project-specific models provide the information for preliminary and detailed designs and independent design verification.
Every project is different. Urban construction with low overburdens may be dominated by settlements of existing structures whereas deep tunnels may be controlled by swelling, squeezing, or rock-burst prone ground conditions. Still other projects may be controlled by time-dependent consolidation or creep processes that have long since occurred or may still occur. At GZ we take all these factors into account to develop project-specific numerical models that accurately reproduce the behavior of their in-situ counterparts. Our models provide important engineering insights into which factors dominate design and construction.
Our staff has been developing detailed 2D and 3D numerical models for over 20 years and since our inception, we have only built upon this expertise. In addition to our practical project-based modeling experience, our staff members have graduate and post graduate degrees and are in collaboration with academia focused on numerical modeling. As a result, we are not only experienced in the use of models for practical construction projects, but are also familiar with the theoretical foundations of Finite Element, Finite Difference, and Discreet Element methods. We recognize better than most that numerical models are tools, and, like any other tools, numerical models are only of use if they are used correctly. When it comes to modeling and simulations, our expert staff guarantees that the right tools are used for each project.
