SEISMIC: Development of Improved Guidelines for Seismic Analysis and Design of Earth Retaining Structures

Recently funded research by Caltrans and other agencies are yielding significant developments in the characterization of earth-retaining structures through large-scale testing and analytical/numerical modeling. There is a need to compile these developments under a unified seismic design guideline for Caltrans-specific earth-retaining structures including abutments, and gravity and semi-gravity cantilever walls.
