Projects constructed in regions with high transient loads (such as wind loads, seismic loads, snow loads, etc.) face unique design challenges. Wind turbines are a common example of structures that are subjected to these high transient loads (in the form of large wind loads). Given the nature of wind turbine structures and the point of load application, the design challenges to be overcome include high foundation bearing pressures, significant overturning moments, minimum rotational/dynamic stiffness requirements, and total/differential settlement design tolerances.
Geopier ground improvement solutions provide site-specific solutions at a considerable cost savings compared to traditional deep foundation approaches or other ground improvement techniques.
Benefits of Geopier Ground Improvement for Wind Farms
- Improved bearing pressure between 5 to 10 ksf needed to the large foundation edge pressures
- Superior settlement control verified by site specific modulus test provides an unmatched level of support and reliability
- Foundation stiffness improvements to deliver the required rotational/dynamic stiffness values specified by tower designers
Subgrade conditions for wind turbine structures are usually the biggest variable in tower foundation design and constructions. Whether your site is challenged by soft clays, loose sandy deposits or organic soils, Geopier design engineers have numerous Geopier ground improvement options to choose from to meet your project's performance needs.
