"Landslide Stabilization"

Dr. Sebastian Lobo-Guerrero

Speaker: Dr. Sebastian Lobo-Guerrero, Ph.D., P.E., BC.GE.

There are multiple ways to stabilize landslides. The presentation covers an overview of different techniques such as mass removal, rock buttresses, geosynthetic reinforced soils, ground anchors, and in particular the use of deep foundations. Slope stabilization with deep foundation elements has become a popular technique in the last 20 years when other techniques are not feasible due to site constrains. The presentation covers a state of the art regarding design and construction of this technology through slide stabilization construction projects developed by the author. In particular the use of micropiles and drilled shafts is highlighted as effective means of slide remediation. The effect of local geology is critical in the implementation of this technology. This is explained through 2 case studies having very different geological models that ultimately determined the remediation technique. The presentation also highlights recent advances in this topic developed by professional associations such as ASCE Geo- Institute and Deep Foundations Institute (DFI).

Sebastian Lobo-Guerrero, Ph.D., P.E., BC.GE. is a highly experienced Geotechnical Project Manager and Laboratory Manager at AGES Inc. in Pittsburgh, PA. He also serves as an Adjunct Professor at the University of Pittsburgh. With 24 years of experience in Geotechnical Engineering, he specializes in the design of deep and shallow foundations, earth retaining structures, and landslide stabilization. Over the course of his career, Dr. Lobo- Guerrero has authored over 250 technical papers and presentations published in scientific journals, geotechnical magazines, and conference proceedings worldwide. He is also a co-author and implementation instructor of the State of Delaware LRFD Bridge Design Manual.

Dr. Lobo-Guerrero has held leadership roles in various professional organizations. He is a former Chair of the Pittsburgh ASCE Geo- Institute and a former Director of the ASCE Pittsburgh Section. He is also a member of the DFI Anchored Earth Retention Committee and served as Conference Chair for DFI-45 in 2020 and DFI-47 in 2022. He is currently on the Board of Trustees of the Academy of Geo- Professionals, ASCE. His contributions to the field have been recognized with numerous awards, including the 2024 ASCE Fellow, the 2022 DFI President's Award, the 2021 ASCE Lifetime Achievement Award, the 2020 ASCE Civil Engineer of the Year (Pittsburgh Section), the 2016 ASCE Geo-Institute Distinguished Reviewer, and the 2006 ASCE Geo-Institute Best Paper on Numerical Modelling
