Wedge Failure Analysis of Soil Resistance on Laterally Loaded Piles in Clay
Publication: Journal of Geotechnical and Geoenvironmental Engineering
Volume 137, Issue 7
Abstract
A fundamental study of pile-soil systems subjected to lateral loads in clay soil was conducted by using experimental tests and a lateral load-transfer approach. The emphasis was on an improved wedge failure model developed by considering three-dimensional combination forces and a new hyperbolic criterion. A framework for determining the curve on the basis of both theoretical analysis and experimental load test results is proposed. The proposed method is shown to be capable of predicting the behavior of a large-diameter pile under lateral loading. The proposed curves with an improved wedge model are more appropriate and realistic for representing a pile-soil interaction for laterally loaded piles in clay than the existing method.
