We’re experienced in the use of techniques such as the Finite Element Method (FEM) and the Finite Difference Method, which are essential tools to model and evaluate potential impacts on infrastructure and the natural environment. Our numerical assessment experience includes evaluation of excavation and tunneling effects in urban areas, stress and deformation analysis of dams, and design optimization of ground improvement under static or seismic conditions. We’ve successfully used these numerical techniques to quantify time-dependent ground movement and stress redistributions due to soil consolidation, creep, soil heave, and dynamic loads. Examples of our application of these numerical tools include: Excavation and construction-induced ground movement Staged construction analysis Retaining wall and excavation support design Foundation settlements Extent and effects of ground Improvement Lateral resistance of deep foundations Complex slope stability analysis Seepage and dewatering analysis Thermal analysis Dynamic soil structure interaction Time-dependent behavior Structural analysis Settlement due to tunneling Numerical modeling programs we use that are widely accepted in the industry include: PLAXIS 2D (with dynamics module) PLAXIS 3D PLAXIS 3D Tunnel PLAXIS 3D Foundation PLAXFLOW FLAC SAP 2000 STAAD Pro STRESS/W and SEEP/W PROJECTS Plateau Creek Pipeline Tunnels Grand Junction, CO NRCS Vero Producers WRE St. Lucie County, FL BCRUA Deep Water Intake Project, Phase 2 Round Rock, TX SEE MORE OUR EXPERTS George R.
