Abstract
The combined Ports of Los Angeles and Long Beach (Ports) have experienced extensive growth over the last three decades. A main feature of the expansions is the creation of new land by placing hydraulic fill behind rock retention dikes. This paper presents an overview of the recent history and state of practice of slope stability analyses performed for projects related to the expansion of the Ports. The geologic and seismic setting and typical soil conditions are also described. This paper is based on a review of geotechnical reports prepared for projects in both Ports and selected published papers. The various investigators used the current state of the practice analyses, with remarkably close agreement in the basic seismic design criteria. The designs and construction practices have, however, varied significantly, particularly in the configuration of the rock dikes (full section and multilift dikes). The design approaches and construction practices in both Ports have been satisfactory as evidenced by the performance of the facilities. Because of different designs located in the same seismic setting and the abundance of quality geotechnical data, the combined Ports offer an excellent opportunity to install field instrumentation to learn from future earthquakes. The conclusions reached and statements made in this paper are solely those of the authors, and do not necessarily represent the opinions of other parties, firms, or agencies involved in any of the projects referenced.
