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

This report presents the "Caltrans Reference Manual for Design of Earth Retaining Structures." It describes the geotechnical and structural design procedures for earth retaining systems in accordance with the general principles and recommendations stipulated in AASHTO LRFD Specifications (2010). It corrects errors in the original edition and makes major amendments to some chapters. The formulation and the derivation of the Composite Log-Spiral Method was examined and several necessary improvements to that model were identified. The improved model, the Log- Spiral-Rankine Model, is based on a limit-equilibrium approach, and accounts for the magnitude of earthquake acceleration, the structure’s height, the backfill soil properties, and the mobilized interface friction angle between the backfill and the earth-retaining structure. Other software developed in the course of this research was used to debug Caltrans' CT-Rigid and CT-FLEX software.
