Slope stabilization with deep foundations elements is a relatively new cost-effective technique that has been used successfully in recent years.
In some cases, it may not be the most economical option compared to traditional methods such as slide removal and embankment reconstruction, but it is often the most cost-effective solution on cases with limited accessibility, concerns regarding safety of excavation, ownership of right-of-way, and closure of communication corridors.
Although this technique has been used frequently in the last decade, there is not a standard code or design manual that covers an accepted design methodology.
The Deep Foundations Institute (DFI) has developed numerous conferences during the last decade where many practitioners and academics have presented general ideas and consensus regarding this topic. These ideas have been gathered on DFI conference proceedings and publications.
The presentation covered some of the main design ideas through the design implementation and construction of slide remediations developed by the author. One example illustrated the case of rockslides where micropiles were used on an emergency job, while a second example considered a soil slide where drilled shafts were utilized. Case studies were explained from design, construction, and performance of these systems, highlighting the lessons learned.
This event was held at Hilton Arlington, 950 N Stafford St, Arlington, Virginia. Attendees received 1 PHD certificate for attendance.
