G.A. Leonards Memorial Lecture: Application of Innovative Geotechnical Solutions

Presented by

Rick Deschamps, Ph.D., P.E - Nicholson Construction


The opportunity to implement innovative solutions generally requires a motivated owner, an unusual problem, reliable geotechnical information, appropriate analytical tools and willingness to try something new. The presentation provides an overview of four projects where innovative solutions were successfully implemented. 1) Construction of a 48 ft cantilever grade change wall to avoid encroachment on neighboring property in Arlington, Virginia. 2) Use of widely spaced deep shear walls to stabilize a slope failure that threatened a key highway in Crookston, Minnesota. 3) Use of a 240 ft diameter diaphragm wall shaft for below grade combined sewer storage, and 4) Use of micropiles to remediate Prairie du Sac Dam that was supported on deteriorating timber piles in Prairie du Sac, Wisconsin.
