Seequent is the subsurface software company within Bentley Systems, the infrastructure engineering software company. Together, we are helping build a more resilient future by connecting the built world above ground with the hidden world below it. Seequent and Bentley’s tunnel design and management workflow is a connected portfolio of solutions spanning ground interpretation, physical modelling, geotechnical design and asset management.
We're thrilled to be attending the largest gathering of tunnelling professionals to showcase our innovative solutions.
We look forward to seeing you at Booth 03:08!
For over a decade, Vienna's Metro extension has been at the forefront of digital transformation in infrastructure and tunneling. It all began in 2012 with the creation of a 3D geotechnical layer model for a single station, quickly becoming an essential tool for tunnel design and construction. Building on this success, a comprehensive ground model was developed for subsequent metro extension projects, leveraging an extensive archive of borehole data to cover significant parts of the city. As technical solutions advanced and model use cases evolved, workflows and model specifications were continuously adjusted to keep pace. This wealth of experience has made digital ground models a standard tool for efficient urban planning.
1:00 - 1:30 PM | Design Optimisation of TBM Starting Shafts Using PLAXIS 3D with Python Scripting Automation
Discover the benefits of using PLAXIS 3D modelling with Python scripting through the example of a medium-sized tunneling project. Along the tunnel route, several shafts were planned, each with different diameters and ground conditions. These shafts included TBM launching and receiving structures, as well as a few intermediate shafts along the tunnel route. PLAXIS 3D was utilized to avoid excessive modelling simplifications regarding ground relaxation caused by sequential drill and blast excavation. The main purpose of the analysis was to optimize the initial support, designed in the form of pattern bolting.
This was achieved by:
- Implementing automation with Python in PLAXIS to search for optimal design solutions across various variants and quickly implement design changes.
- Importing layering and material properties from an external Excel file to define the ground models.
- Speeding up shaft geometry definition in the tunnel designer using Python scripting.
- Automatically defining phases based on geometrical assumptions for each shaft.
- Customizing post-processing of results for efficient design report preparation.
