Overview of Recommended Analysis Procedures for Pile Foundations in Laterally Spreading Ground

This paper presents an overview of a report presenting recommended analysis practice for pile foundations for bridges in laterally spreading ground under development for Caltrans by the authors. The past decade of research has produced numerous insights into the behavior and performance of pile foundations and bridges impacted by liquefaction and lateral spreading. The purpose of the report is to develop a set of recommended procedures and practices for analysis and design that are based on a synthesis of research findings when supporting research is available and on the professional opinions of the authors when supporting research is lacking. The scope of the report is to summarize those recommendations in a concise document that provides references to supporting materials and/or identifies areas where supporting materials are lacking. While the report is currently under development, this paper presents an overview of the guidelines, essentially introducing topics that will be covered in each chapter.
