PLAXIS 3D: 3D Geotechnical Numerical Modelling

Export a 2D embankment to 3D with the Plexus 2D to 3D converter and extrude perpendicularly. Model materials, apply surcharge, mesh, run staged construction, and assess the factor of safety.

Plexes 3D: set up a new project, define axes and the origin, create boreholes and stratigraphy, assign soil materials, and generate a 3D mesh while exploring the viewing options.

Draw points, lines, and polygons or surfaces in the structure tab using top view and z coordinates. Set planes, apply loads and prescribed displacements, and extrude elements into volumes.

Learn to clone and array elements, move and rotate objects, and create lines, surfaces, plates, and piles in Plaxis 3d, with isotropic concrete materials.

Learn to draw and place ground anchors and embedded beams using plates, lines, and line angles, set coordinates and lengths, and apply appropriate boundary conditions in a Plaxis 3D model.

In Plaxis 3D, model a bridge pier foundation with a six-pile cap over a three-layer stratigraphy of top sand, middle sand, and soft rock, using a hardening soil model.

Define a piles material with unit weight 25 and e 48.3 gigapascal for a 1.2 m pile. Set multilinear axial skin resistance, end bearing, and design pile cap with loads.

Analyze a raft foundation for a high-rise with two basements and a 20 by 20 meter raft. Model phased steps—geostatic stresses, diaphragm walls, dewatering, excavation, and consolidation to 90 percent.

Build a soil model and raft foundation in plaxis 3d, set the raft at -6 m, add diaphragm walls with embedment, apply surface loads, mesh, and compute initial stresses.

Explains continuing analysis by installing a diaphragm wall, performing dewatering, and setting groundwater levels, then sequencing phases from dewatering to excavation with consolidation and pore pressure monitoring.

Activate a raft consolidation phase, simulate 30 days of dewatering and serviceability loading, then assess pore pressure, phreatic level, and maximum settlement to verify 90% consolidation.
