ACEC Oregon / SW Washington Public Agency Liaison Committee Meeting

PRESENTATION
Landslide Mitigation using Anchored Shear Piles

PRESENTER
Tom Westover, PE, Associate Engineer
Cornforth Consultants, Inc. 




Multnomah County, Oregon is replacing the Sellwood Bridge within its existing footprint. The original bridge was built in 1925 at the site of an ancient landslide located along the west bank of the Willamette River. The landslide, approximately 800 feet long, 500 feet wide, and 50 feet deep, has moved in excess of three feet toward the river channel during the bridge’s 90-year history, which caused severe buckling and cracking of the old bridge deck and abutment piers. The landslide movement was mitigated using an anchored shear pile (ASP) system. Structural mitigation of landslides is increasingly necessary where existing geologic hazards intersect with displacement-sensitive infrastructure. Anchored shear piles (ASP) can be used to develop full-depth restraint of large landslide masses with limited post-construction deformation. This presentation highlights a case study for landslide mitigation through the use of high-capacity ground anchors integral with cast-in-place concrete shear piles. Construction of an ASP system can provide full-depth resisting force to a landslide, without the risk and right-of-way impacts of large open-cut excavations.  

ABOUT THE PRESENTER
Mr. Westover has 8 years of geotechnical engineering experience in the Pacific Northwest. His expertise includes design and testing of high-capacity ground anchors, soil-structure interactions, anchored shear pile design, geotechnical engineering for transportation applications, landslide evaluations, rockfall mitigation and design, 3D modeling and visualization, in-situ stress determination, construction sequencing on landslides, and constructability. He is a registered civil engineer in Oregon and Washington.
