Purpose and Background
These presentations were recorded at the 2024 Geo-Structures Conference.
Rigid Inclusion Support for Transportation Projects (46 minutes)
This presentation explores the application of rigid inclusions in transportation infrastructure, offering a detailed analysis of their design, implementation, and effectiveness. The speaker discusses how these engineered elements enhance ground stability, reduce settlement, and provide cost-effective alternatives to traditional deep foundation methods. Through real-world case studies, attendees will gain insights into best practices for integrating rigid inclusions into embankments, bridge abutments, and roadway support systems. The session also examines lessons learned from past projects, the evolution of rigid inclusion specifications, and how innovation is reshaping geotechnical design strategies.
Bridging the Gap: Rapid Reopening of Philadelphia I-95 Bridge After the Collapse (17 minutes)
This case study showcases the remarkable engineering and construction effort that led to the rapid reopening of the Philadelphia I-95 bridge after a catastrophic collapse. The session covers the immediate response, challenges in rebuilding, and the geotechnical solutions that made reopening possible in just 12 days. Key topics include the use of lightweight foam glass aggregate to reduce embankment load, the design and construction of a temporary MSC wall, and the collaborative approach between engineers, contractors, and government agencies. This presentation provides valuable insights into emergency infrastructure response, demonstrating the critical role of innovative geotechnical engineering in restoring essential transportation routes.
Innovations in Rehabilitation of Aging Bridge Abutments (15 minutes)
Aging bridge abutments present significant maintenance and safety challenges, requiring creative and cost-effective rehabilitation solutions. This presentation examines modern approaches to strengthening, stabilizing, and extending the service life of deteriorating bridge substructures. Through case studies, the speaker highlights techniques such as micropile underpinning, soil nail stabilization, and geosynthetic reinforcement. The session also explores how innovative access techniques, such as rope-assisted stabilization and limited-access drilling, allow for efficient repairs while minimizing environmental and operational disruptions. Attendees will gain a deeper understanding of how these rehabilitation strategies can enhance structural integrity and prolong the lifespan of critical transportation assets.
