Road and rail earthworks design
|
|
Today, we are discussing road and railway embankments.
The design of earth embankments, i.e. structures built using loose soils, primarily aims to ensure stability over time while maintaining adequate safety margins. The performance requirements vary depending on the type of structure. For instance, in the case of an earth dam or a river embankment, hydraulic impermeability is a critical requirement, whereas for road or railway embankments, the primary concern is ensuring safe and durable passage.
The stability of embankments, like other earthworks, is closely linked to their interaction with the underlying soil. The loads transmitted from the embankment to the foundation soil can reach several tens of tons per square meter, potentially affecting even deep soil layers.
However, when built on weak soils, it is necessary to assess the risk of instability and account for potential settlements, both immediate and long-term, caused by soil compression.

What's new in Loadcap 2025
| |
|
Loadcap 2025, enables users to perform all relevant checks for embankment stability in accordance with and Eurocode 7.8.
Consolidation works can be applied using gravel piles with recalculation of the ultimate load and settlement.
When using gravel piles, the software calculates the settlement associated with the lowering of the water table.
The embankment stability checks can also account for the self-weight of the embankment in addition to the load from road traffic.

SLU, SLD and SLE checks
|
|
Safety checks for the SLU (Ultimate Limit State) are conducted through design strength calculations in the vertical direction, including checks for crushing, sliding, and global stability (with Slope interoperability).
For SLD and SLE checks, the software calculates elastic and oedometric settlement (derived from the oedometric curve) in three dimensions (x, y, z) and over time, capturing the evolution of settlement.

Interoperability and with Calculating flexible and semi-rigid road structures - RPD
|
|
From version 2025 of the software Road Pavement Design - RPD will be interoperable with Loadcap!
