Abstract:

This report summarizes the findings of a study on the use of multiple small-diameter cast-in-place piles to control landslide movements. The report summarizes various mechanisms by which the piles could respond to prevent landslide movement and presents a brief history of applications. During the performance of this study, two sites at which small-diameter cast-in-place piles were installed for landslide repair were instrumented. The purpose of the instrumentation which primarily consisted of strain gages mounted on the steel reinforcement bars within the piles was to provide data so that the resisting mechanism occurring within the pile structure could be determined. At one of the sites the New York site, the instrumentation revealed data that were consistent with the design assumptions. At the other site the California site the results were inconclusive because of post-construction movements and because loads did not occur to any significant extent.
