Sustainable Practices in Mitigating Liquefaction-Induced Foundation Settlements: A Focus on Carbon Footprint Reduction During Sheet Pile Design-Video

Video Transcription

Video Summary

The study evaluates full-length and partially floating sheet piles for reducing shallow-foundation settlement during liquefaction, while comparing their material use and embodied carbon. Shake-table tests showed that both configurations reduced settlement and tilting compared with an unmitigated foundation, with performance differences of about 10% for settlement and 3% for tilting. The partially floating design used about 9% less material and embodied carbon while providing similar performance. The carbon analysis considered only material production. Limitations included low achievable shaking intensity and a small-scale model; future work will assess other mitigation methods and additional life-cycle stages.
