Part 1: Estimating and Minimizing Movements using PLAXIS 2D: Haley & Aldrich Case Study on Slurry and Secant Pile Wall Design

The Tangent and Secant pile systems are commonly used in geotechnical engineering to support excavations. However, the design process can be complex, often leading to the adoption of overly conservative analyses, which in turn increases cost.

PLAXIS, a powerful tool for a wide range of geotechnical analyses, ensures design optimization and cost savings.

Join our product expert Richard Witasse and Wystan Carswell from Haley & Aldrich for a live webinar. Wystan will present a case study on the use of PLAXIS 2D in the design of a support of excavation (SOE) system for the Lyrik Back Bay - Air Rights Parcel 12. This project is the first successful air rights development over the Massachusetts Turnpike (Interstate I-90) in 40 years. It features the innovative use of slurry walls and secant pile walls as key components of the excavation support design. The analysis also includes estimations of the movement of adjacent buildings, roadways, and railroad tracks. Discover how PLAXIS can help you save both time and money in your SOE analysis.

What you will learn: 

• Efficient ways to set up slurry and secant pile wall designs using PLAXIS
• How to fast-track your analysis by selecting the right constitutive models and input parameters
• How to visualize and interpret the results of slurry and secant pile wall analysis in PLAXIS
