Regarding the 20-minute webinar, which will be followed by Q&A, Schimmel writes:
The construction of embankments on soft soils can be very challenging from both the design and construction perspectives. Many alternatives are available, but in most cases geosynthetics are the most efficient and economical solution. Geosynthetics on such applications function as soil reinforcement, increasing stability while allowing for faster construction and steeper faces. This webinar will offer an overview of solutions for embankments founded on poor soils utilizing high-strength geotextiles, geogrids and geotextile encased columns (GECs) as deep foundations.
SOFT SOILS WITH GEOTEXTILE-ENCASED COLUMNS
The use of geotextile-encased columns is a strong inclusion in the webinar. HUESKER recently shared a videocast about GECs. The system was developed as a foundation solution for earthwork structures built on weak subsoils.
GECs create a pile-like, load-carrying system that is a quick, cost-effective method of providing a foundation for embankments on ground with low-bearing capacity. One of its advantages stems from its utilization of circular-loom technology, which eliminates weak points and loss of strength caused by joints, e.g. seams, or discontinuities in the design-relevant stiffnesses.
The company’s Ringtrac® reinforcement sleeves offer a number of engineering highlights, including:
- Reduction of creep settlement by 50 – 75%
- Up to 90% of the consolidation takes place during construction
- Secondary settlements are low and can be mitigated by temporary surcharge
- Able to be used in extremely soft soil (e.g., undrained shear strength < 15 kPa)
- Loadable immediately after installations
- High embankments can be built in short time with no danger of base failure
- System is highly adaptable to local conditions and loads
- Economical use of site space and lower excavation, disposal and imported material costs
- Reduction in construction time and cost
- Non-rigid system, dynamic loads (e.g., from passing trains) can be accommodated without damage
- Accelerated consolidation
- 15+ years of projects on record
