If you are a geotechnical engineer or a rock mechanic, you know how important it is to have a reliable and accurate software for designing and analyzing soil and rock structures. You need a software that can help you perform complex calculations, simulate realistic scenarios, and visualize the results in an intuitive way.
Plaxis 3d Foundation 22 178
That's where Plaxis 3d Foundation comes in. Plaxis 3d Foundation is a user-friendly, finite element package with trusted computation that is used by geotechnical engineers globally. It offers CAD-like drawing capabilities to help you create a 3D model of your subsurface environment for geoengineering projects. You can then perform advanced finite element or limit equilibrium analysis of soil and rock deformation and stability, as well as soil structure interaction, groundwater, and heat flow. You can also view and interpret the results using various output options, such as contours, vectors, graphs, tables, animations, and reports.
In this article, we will introduce you to Plaxis 3d Foundation 22 178, the latest version of this software that was released in June 2022. We will show you how to use it, what are its main features and benefits, and how it compares with other versions of Plaxis 3d. We will also share some case studies of how Plaxis 3d Foundation was used in real-world projects. By the end of this article, you will have a better understanding of why Plaxis 3d Foundation is one of the best software for geotechnical engineering and rock mechanics.
How to use Plaxis 3d Foundation 22 178
To use Plaxis 3d Foundation 22 178, you need to have a valid license and subscription. You can buy or try the software from Bentley Systems or Seequent , depending on your region. You can also get access to online training courses, tutorials, manuals, forums, and support from these websites.
Once you have installed and activated the software, you can start creating your 3D model of soil and rock using the CAD-like drawing capabilities. You can import existing geometry from other software or draw your own using various tools, such as points, lines, surfaces, volumes, boreholes, tunnels, anchors, piles, beams, plates, interfaces, etc. You can also assign material properties and boundary conditions to your model using predefined or custom models.
After creating your model, you can perform advanced finite element or limit equilibrium analysis of deformation, stability, groundwater, and heat flow. You can choose from different types of analysis modes depending on your project needs, such as static analysis (for linear or nonlinear behavior), dynamic analysis (for seismic or traffic loading), consolidation analysis (for time-dependent effects), safety analysis (for factor of safety calculation), etc. You can also use various features to enhance your analysis accuracy and efficiency such as mesh refinement (for local detail), staged construction (for sequential loading), multicore solver (for faster computation), etc.
Finally, you can visualize and interpret the results using various output options. You can display the results in different ways such as contours (for stress or strain distribution), vectors (for displacement or velocity direction), graphs (for force-displacement curves), tables (for numerical values), animations (for time-dependent behavior), reports (for documentation), etc. You can also export the results to other software for further processing or presentation.
Case studies of Plaxis 3d Foundation 22 178
To illustrate how Plaxis 3d Foundation can be used in real-world projects, we will share some case studies from different countries and domains.
Design and analysis of foundation slab for bridge in Korea
In this case study , Plaxis 3d Foundation was used to design and analyze a foundation slab for a bridge over a river in Korea. The foundation slab was designed as a reinforced concrete structure with dimensions of 40 m x 40 m x 1 m. The soil conditions consisted of soft clay with low bearing capacity and high compressibility.
The main objectives of the analysis were to evaluate the settlement, stability, stress distribution, and reinforcement ratio of the foundation slab. The analysis was performed using static analysis mode with nonlinear material models for soil and concrete. The loading conditions included self-weight, bridge weight, traffic load, wind load, water pressure, etc.
The results showed that the maximum settlement of the foundation slab was about 15 cm under service load condition. The factor of safety against bearing capacity failure was about 4.5 under ultimate load condition. The stress distribution in the foundation slab was uniform except near the edges where stress concentration occurred. The reinforcement ratio was about 0.5% for both directions.
Evaluation of effect of sedimentation on anchorage performance for long-span bridge
In this case study , Plaxis 3d Foundation was used to evaluate the effect of sedimentation on anchorage performance for a long-span bridge over a sea. The anchorage system consisted of pole-concrete drift cable (PCDC) and piles. The PCDC was composed of two steel pipes filled with concrete connected by a drift cable at an angle of about 45 degrees. The piles were driven into the seabed at an angle of about -15 degrees.
The main objectives of the analysis were to investigate the influence of sedimentation on PCDC structural performance and piles anchorage capacity. The analysis was performed using consolidation analysis mode with coupled flow-deformation calculation. The loading conditions included self-weight, cable tension force, wave load, etc.
The results showed that sedimentation had a significant impact on PCDC structural performance and piles anchorage capacity. Sedimentation caused an increase in axial force and bending moment in PCDC components due to the reduction in effective stress around them. Sedimentation also caused a decrease in pile-soil interface friction due to pore pressure dissipation. These effects reduced the safety margin against structural failure or pull-out failure.
Simulation of seismic response of tunnel in Japan
In this case study , Plaxis 3d Foundation was used to simulate the seismic response of a tunnel under an expressway in Japan. The tunnel was constructed by cut-and-cover method with dimensions of 20 m x 10 m x 300 m. The soil conditions consisted of sand layer overlying clay layer with high liquefaction potential.
The main objectives of the simulation were to evaluate the dynamic behavior of soil-tunnel system under earthquake loading and to assess the damage potential of tunnel lining due to ground deformation. The simulation was performed using dynamic analysis mode with nonlinear material models for soil and concrete. The earthquake loading was applied as acceleration time history at bedrock level.
The results showed that significant ground deformation occurred due to liquefaction of sand layer during earthquake shaking. The maximum horizontal displacement reached about 1.5 m at the ground surface and about 0.5 m at the tunnel crown level. The maximum axial strain in the tunnel lining was about 0.2%, which exceeded the allowable strain of 0.1% for concrete. The maximum bending moment in the tunnel lining was about 100 kN-m/m, which was lower than the design value of 150 kN-m/m. The results indicated that the tunnel was vulnerable to liquefaction-induced damage due to large ground deformation and axial strain.
