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.

What is ASCE-NCS?

Welcome to the website of the National Capital Section of the American Society of Civil Engineers (ASCE), a professional society for civil engineers.  ASCE was founded in 1852, represents 130,000 members of the civil engineering professional worldwide, and is America's oldest national engineering society.

The National Capital Section was founded in 1916 and currently has more than 3,100 members.  The section is located in Region 2 (link to region 2: The National Capital Section serves the District of Columbia; the counties of Montgomery and Prince Georges in Maryland, except College Park in Prince Georges County; the counties of Fairfax and Arlington, and City of Alexandria in Virginia. The National Capital Section's mission includes:

  • To advance the professional knowledge and improve the practice of civil engineering for our members and those we serve.
  • To advocate for our profession with those whose actions affect us, and to educate those whose actions and responsibilities could benefit from a better understanding of the contributions of civil engineers.
  • To improve our community through effective community outreach programs, local involvement and educational efforts.
