Stability Assessment of a Deadman Anchor Pile Close to the Bulkhead Wall-Video

Video Transcription

Video Summary

Wenjun Dong presents a stability assessment of a waterfront bulkhead wall and nearby shoring pipe piles proposed as anchors. Analyses show the cantilever wall has a factor of safety of about 1.1, while a top tieback raises it above the 1.5 criterion. Because the anchor piles are close to the wall, their passive soil resistance is truncated. Dong proposes a truncated-wedge method to estimate this resistance and applies it in limit-equilibrium and LPILE analyses. Results indicate that piles less than 40 feet from the wall may lack sufficient geotechnical or structural capacity.
