Seismic performance evaluation of geotechnical structures

Abstract

The paper describes an emerging methodology for evaluating seismic performance of geotechnical structures that extend over tens of kilometers along a coastal protection line. The challenging aspect in establishing this type of methodology for performance evaluation is in the fact that site-by-site detailed study is not practical. The paper proposed a performance-based approach utilizing simplified design charts that are newly developed based on a parameter study of effective stress analyses of soil-structure systems. The coastal protection lines over a distance of 70km along Osaka Bay Area, Japan, are used as an example to demonstrate the advantages of the proposed approach. © 2008 Science Press Beijing and Springer-Verlag GmbH Berlin Heidelberg Geotechnical Engineering for Disaster Mitigation and Rehabilitation.
