PLAXIS 3D Railway Track Modeling

Job ID: 40567571

Budget: $100 – $800 AUD

Project Title

PLAXIS 3D Modelling of Geogrid-Reinforced Ballasted Railway Track

Project Description

I am seeking an experienced PLAXIS 3D engineer to develop a complete geogrid-reinforced ballasted railway track model from scratch for my Master's research project. I also want to learn the complete modelling workflow, so the selected freelancer should explain each step, modelling assumption, and interpretation of the results throughout the project.

Scope of Work

Develop the complete PLAXIS 3D model, including:

Rails

Concrete sleepers

Ballast

Sub-ballast/Capping

Subgrade

Geogrid reinforcement


Perform dynamic moving-load analysis.

Conduct parametric studies for:

Geogrid stiffness

Wheel load variation

Train speed variation

Pore-water pressure conditions


Explain the modelling methodology, assumptions, and engineering reasoning behind each simulation and result.


Deliverables

PLAXIS 3D project files

Time-history plots (vertical displacement, lateral displacement, and vertical stress)

Peak value and comparison tables

Summary graphs

Engineering interpretation of all results

Step-by-step guidance so I can confidently understand and reproduce the modelling independently


Requirements

Proven experience with PLAXIS 3D

Experience with dynamic/moving-load analysis

Experience in railway geotechnical engineering or geosynthetic/geogrid modelling is preferred

Strong communication skills and willingness to teach throughout the project
